Done some refactoring: - Moved includes into the cpp files where possible and using class pre-declarations if possible - Made class member variable names begin with an underscore - Made by uic created header files be used as class members instead of inherting them - Renamed some variables to reflect their purpose better - Added some NULL initializations and added some comments - Rearranged some include and declaration code parts to be consistent and better readable - Updated for QScintilla 2.4.5 - Made UiGuiSettings be accessed via a shared pointer only git-svn-id: svn://svn.code.sf.net/p/universalindent/code/trunk@1028 59b1889a-e5ac-428c-b0c7-476e01d41282
