[texworks] PAtch for .desktop file and building texworks Rev720 with libqt4 < 4.7

[Atri]

Hi!

With the latest svn revision, building texworks from source fails unless
libqt4 version 4.7 is used. With libqt4 versions 4.6.x and 4.5.2+, I
keep getting errors like the following while building

----------------------------------------------------------
src/TeXDocument.cpp: In member function 'void
TeXDocument::reloadIfChangedOnDisk()':
src/TeXDocument.cpp:1129:44: error: 'class QDateTime' has no member
named 'msecsTo'
src/TeXDocument.cpp:1133:41: error: 'class QDateTime' has no member
named 'msecsTo'
make: *** [obj/TeXDocument.o] Error 1
----------------------------------------------------------

Also, I use a patch to fix little complaints in the .desktop file
reported by RPMLint when it looks for problems with a built rpm package.
This patch removes the first shebang line from the .desktop file and
completes the Categories definition in it. Here's the patch
