Changing from Macports to Jhbuild

[ghost]

I had to add libsqlite3 and libz in static linking to make it work.

This works great, now! Do also update the BUILDING.md file to include the required jhbuild build meta-gtk-osx-python step. I also had to delete my .jhbuildrc-custom file and allow the gtk-osx-build-setup.sh script to recreate it because it was incompatible with a recent update, but I don't know that that belongs in our documentation.

Commit away!

@W0naN0w Found a slight problem: the MAC_FLAGS variable is not part of the configure script, so @MAC_FLAGS@ will not be substituted during configure. For OS X, this isn't a problem because we pass MAC_FLAGS on the command line, but for other platforms, it results in the literal string @MAC_FLAGS@ being passed to the linker. The line should instead be an empty assignment:

MAC_FLAGS=

This ensures it will be blank unless it is passed via the make command line.

@dmiller-nmap, I just opened a new PR, #457 to update this one. I also updated BUNDLING.md directly on the svn trunk with the following changes:

• Add .jhbuildrc-custom to the rm command at the beginning of the file
• Add the jhbuild build meta-gtk-osx-python step

Thank you again for all your work!
