Merge branch 'maint'
Fixed package dependencies for gnuradio-core and gr-wavelet, added support for Ubuntu 12.04 and Fedora 17
docs: adds a 'make sphinx' target that can be run after 'make install' to generate the Python docs.
cmake: make a find portaudio that follows the rules
cmake: fix pygtk check failure with no X session

This change helps to build gnuradio on systems which have a libjack.so library available for compatibility purposes without the header files (like gentoo where libjack.so is part of app-emulation/emul-linux-x86-soundlibs)....
Removed whitespace and added dtools/bin/remove-whitespace as a tool to do this in the future.
The sed script was provided by Moritz Fischer.
