OSX and Allegro fixes for GWEN
Update gwen/Projects/premake4.lua

targetsuffix appends the specified parameter to the end of the project name.
targetextension replaces the extension with the specified parameter.

The samples look for "gwen-staticd.lib", but if you use targetextension the only thing that is created is "gwen-staticd".

Without this fix the samples won't compile when set to debug mode.

Fix the SFML renderer to work with non-MSVC compilers
Merge pull request #24 from Simononon/master

Fix the SFML renderer to work with non-MSVC compilers
Fix for TextBoxes not moving the text in text boxes when moving the
carat or adding characters that exceed the textbox's visible space.

- Adds empty PostLayout() in TextBox class to avoid Label's PostLayout
  from being called. Otherwise the text's position will always be set to
  a fixed position defined by the alignment.

Misc changes:
- Removed extraneous semicolon in TextBox::MakeCaratVisible()
- Added newline in TextBox.cpp to avoid GNU compiler warnings
Fix for crash when exiting OpenGL samples

Cause:
- Order of operations was causing the crash. The OpenGL renderer was being
  deleted before the TexturedBase skin, which depended on it.

Fix:
- skin was changed to a pointer, allowing it to be deleted before the
  OpenGL renderer.
Added newline at end of OpenGLSample
