Added some javadocs
Fixed a couple bugs in the attribute manager
#26: Made changes to the class view and classes that use it so that tags mapping to classes in the same toolkit as an ancestor (or in the toolkit that a style sheet belongs to) may be specified without explicit namespace specification.
Removed the AttachPoint and AttachPointOverride tags from the Template annotation schema.
Fixed a strange line of code that was causing resource finding to break.  Don't know why it was there.
Fixed some indexing problems in mutating message center
Converted Button to a template widget and updated ButtonTest.
#32: Got the button template sort of working.  It actually looks like the template part is working perfectly, but now there's a problem where style sheet property specifying the button's texture is being inherited by the button's content pane (a block).  So it looks like a button within a button.  No obvious way to fix this easily.
Added classes to .gitignore in all projects
