EiffelStudio 64bit full changelog

· studio: Made sure that conditions in Project settings are human readable. This fixes bug#18519.
· studio: Fixed bug#18504 when adding removing libraries to a project.
· compiler: Fixed a regression where using the compiler option `-safe' will not work anymore if you apply it to ECFs already containing some ECFs without a corresponding -safe ECF.
· compiler: Fixed a bug where after a finalization, the printed message was always mentioning the workbench version.
· library: Updated FILE/DIRECTORY classes to recent changes in the compatible version so that gobo descendants can compile.
· compiler: Fixed bug#18509 and eweasel test#config036 where the library_target of an ECF was not compared in a case insensitive manner with the name of the target thus causing an error if the target name was anything but lower case. Improved error messages by using the name as specified in the ECF (i.e. no lower case conversions).

· library (base): Added support for converting CHARACTER_32 to lower or upper case.
· installation: Added support for Visual Studio 2012 as a C compiler backend.
· library (base): Added support to manipulate Unicode path.
· Added support for installing EiffelStudio in a path with Unicode characters.

Improvements:
· compiler: bug#17591, bug#17662 (test#pretty028) - Improved formatting of comments delimited with blank lines.
· vision2: one can now provide a hint of the size of the dropdown list of the combobox. The hint is currently only effective on Windows.
· vision2: Improved the default size of the dropdown list of a combobox so that all the text can be visible.
· compiler: test#valid275 - Reduced the number of cases when VWEQ warning is reported, in particular by limiting it to the immediate code only.
· compiler: test#tilde002 - Optimized code generation for the equality test that involves two values of different expanded types.
· compiler: bug#15145 (test#exec296) - Supported detection and warning report with code VWAB for useless bodies of attributes that are never executed because the types of the attributes are self-initialized (expanded or detachable).

Improvements:
· compiler: Avoided reporting errors related to variable initialization when the right-hand part of assignment to this variable causes an error.
· compiler: Promoted keywords across and some from provisional syntax to the standard one.
· compiler: Made class BIT_REF optional as soon as a BIT type is not used in a system.
· studio: Replaced keyword completion for indexing with keyword completion for note.
· Feature removed

Bug fixes:
· compiler: bug#16974 (test#term187) - Fixed a bug that caused a compiler crash on a particular kind of formal generic constraints.
· compiler: bug#17057 (test#term190) - Fixed processing of invalid formal generic constraints that could potentially lead to a crash.

· Feature removed

· studio: Fixed regression where one could not either create a new editor tab, nor could you close any tools.
· studio: Fixed the incorrect pick and drop line.
· compiler: Fixed various inlining bugs, see eweasel test#final102, test#final103, test#final105 and test#final106.
· compiler: Fixed a bug in the finalization of an agent call with a tuple involving the third or greater formal generic parameter of the class (eweasel test#agent014).

· Compiler: Allowed for a qualified anchored type that has a standalone type qualifier to be used as a type of a once function (bug#16947, test#anchor050).

· Bug fixes
· Compiler: Fixed eweasel test#incr366 when an expanded generic type is being used and its expandness status is removed. It completes the fix for test#incr315.
· Compiler: Fixed test#attach077 when VEVI was not properly reported in some cases for uninitialized attributes passed as arguments.
· Compiler: Fixed eweasel test#incr378 for a bug added at the previous intermediate release which would break execution of code when touching/modifying some generic classes used in the system.
· User changes
