Fixes #18

Adds admin create round link on /admin/roundlist

Hides all unusable form inputs on creation, can simply type name of
theme and hit enter.. 

Discovered rounds table doesn't use auto-incrementing values for the
"number".. which, while it has a use-case, definitely isn't useful..
surely there should be an id number that is unique or something..
anyway, it works.
I'll push it live
