Colons in wiki page titles, and commit fest page names

I don't know how the page naming like Todo:Detail and CommitFest:March page 
naming got started, but it is not how other mediawiki sites use it.  I think 
Todo/Detail and CommitFest/March would be more usual.  Then you could also 
create a CommitFest index page and have natural path names.

While some change might be pending, I think it'd also be forward looking to 
put year numbers in the commit fest page names.

Any objections to making these changes?
