Dropbox Index with link to freedns as well as correpsonding css.
Added css changes.
Merge branch 'master' into dropbox
Fixed a bug in the saving feature cutting of the towers on the right and bottom side.
Lots of changes

- Overlay is drawn correctly on 1x1 towers
- deleting big towers with smaller ones does not render the maze unusable due to not all blockers being deleted
- Options look nicer now and started to add custom tower size
- Path Calculation stops when the next waypoint cannot be reached
Merge remote-tracking branch 'remotes/origin/dropbox'
Tower-size can be changed in the settings. Overlay also displays this size (except for shift/alt)
