In some cases Qt Creator will create a CMakeLists.txt.user file with a short hash which should also be ignored. For example:

    CMakeLists.txt.user.1fa15d5

Qt generates build files for me that are `build-Projname-WhateverWhatever` so this change continues to support *-build-* folders as well as others.

- Ignore '*.moc' files (foo.moc created when foo.cpp contains a Q_OBJECT.)
- Ignore '/.qmake.cache' and '/.qmake.stash' as does the official Qt Creator project.

moc automatically generates "ui_*.h" files for each *.ui file.
Since they are auto-generated I assume they should be ignored.

With "CONFIG=debug_and_release" qmake generates both Makefile.Debug and
Makefile.Release. And I assume it is useful to have all types Makefiles
ignored.
