[xwiki-devs] ExtendedTodoApplication

I've made quite a few improvements to the original TodoApplication, and was told to send it here for review. First, here's a list of introduced features: * extended Todo class * revamped class sheet/template * revamped webhome (many improvements) * ability to add todo's right from side-panel * ability to show completeness percentage * more.. The naming was suggested by 'jvelociter' (on irc) due to the fact that the TodoApplication is used for a tutorial and must be kept simple.. suggestions are welcome, I've tinkered with the todo panel to make it more compatible with toucan and albatross based skins just before i sent this to you, so tell me if you have any takes (i.e. if it looks ugly)..
