doc/release-process.txt: This adds some reminders to release-process.txt to bump build numbers in the code and the new OSX app bundle.
contrib/Bitcoin.app: Adds the OSX App Bundle itself. (Originally from Laszlo Hanyecz solar@heliacal.net waiting on email response the list is cc'ed on to confirm licensing semantics.)
doc/build-osx.txt: Fixes line wrapping to be consistent. Fixes hard tabs to be spaces. Fixes checkout instructions to actually give the correct location on github instead of old SVN repo. Changes path ~/bitcoin/trunk to ~/bitcoin/bitcoin/src to be in-line with current source layout. Changes instructions for putting the resultant binary into the App Bundle. Adds notes on openssl/bdb/miniupnpc/wx builds about system versions and macports versions.
