Fix DrawLine bug

lol nemo, lol

tweaks to sea ice appearance

Possibly fixed issue #533.

Resolves issue #528. Fixed platform-specific order of buttons on seed prompt and new room prompt. Fixed height of back button on all pages -- now aligns to bottom. On pagemain, feedback and dlc buttons no longer fixed size.

my turn to do a neglected merge for someone else

Review the list of synced messages in isSyncedCommand. Fixes issue #546.

Made pressing the button in mapContainer only randomize things if client is master. Fixes issue #545. Also synchronized themes. Fixes issue 547.

avoid floating point desync, other script tweaks

So. A while ago, while trying to prevent hogs blowtorching getting turned around, unc0rr altered the old range of blowtorch from 1/8th of 180° up or down, to a 4° gain in upwards and a -4° loss in downwards. He also made it so that starting tunnels could fail to erase sufficient terrain, trapping hogs. Here are a couple of workarounds to more closely approximate old behaviour (do some initial erasure, adjust min/max angles)

Safety check. The main place this can be a problem is on a mild bowl w/ multiple hogs. Could possibly add a hog collision check in here.

split version information in engine too

drop useless option, automatically set revision and debug info

split cVersionString into its three separate components (version, revision, hash) and apply the new values sensibly on the frontend (esp. title, info and feedback)
