Migration and upgrade

Hi, sorry for the downtime! The wiki crashed again, so I took the last backup I had and have put it onto an upgraded mediawiki on a new host. Hopefully no more stability issues!

There are a few known issues:

• The backup is only from October last year :( All new users, pages and edits since then are lost, at least for now. Working on this.
• The RumbleStats extension uses deprecated and removed functions in Mediawiki, and the changes I made to at least have it not crash the wiki don't result in it working. If anybody wants to help I'm happy to give server credentials.
• No twitter in the tools sidebar
• Images on the old wiki still broken
• The URLs now have index.php in them, and my attempts at fixing this so far break everything. I'm probably missing some Apache setup somewhere.

On the other hand:

• Upgraded mediawiki
• Emails working again
• New Robocode-specific captcha, so I've re-opened signups.

Anyway, welcome back, and happy Robocoding!

Fixed:

• Images on the old wiki
• Short URLs again, same as before, so the rumble clients should be happy.

Still missing:

• RumbleStats
• Twitter sidebar
• Backup is old

Surely I would like to help with RumbleStats.

Btw we still have the data since Oct. last year on the original host right? Can we merge database so we don’t lose changes from here.

Hopefully the old data can be recovered. But it might take some time.

Btw literumble seems to crash, right after I started 8 roborumble instances...

It used to work OK, but now it returns http 500.
