Overhaul the haiku-apps directory

* Fixed PROVIDES/*REQUIRES entries
* Added vcs hashes to the ports needing it in the SRC_URI
* Made single executable apps install to the top level $appsDir
* Added patches for gcc4 versions of most apps
* Added patches for apps that couldn't build on any arch
   ( even though they were marked as working :( )
* Other misc fixes that I've forgotten already because I'm sick of
  looking at this directory
