Darcs/patch-tag -> git/github migration

All the diagrams repos are now migrated to github, under the diagrams organization.

What still needs to be done:

• Import issues from Google code into github. However, the github issue trackers are per-repo, so we'll have to import according to 'Component' tag (and the component tags may need to be cleaned up on google code first). fryguybob thinks maybe we can modify this to get something that will work.
• Update any and all references to patch-tag to point to github instead. This includes:
  • The diagrams website
  • The user manual and tutorial?
  • The packages themselves (in the .cabal files)

Guidelines

• Coding style guidelines. It's not worth being super picky about these, but in general they are quite good.

• Guidelines for reviewing and merging code. For those with push access to one or more repos in the github diagrams organization.

Design notes

• Text support
• Notes on extending support for paths
• Bounding functions
• Freeze, attribute transformation, and the backend API
• Notes on the representation of transformations: linear and affine transformations, inverse, transpose, etc.

Releases

• 0.5 to 0.6 migration
