SMD: Fixed wrong preview radius and added RULEUCC_Pause

* EffectiveRadius was 75 when the actual radius of the weapon is 90
* Can't see a reason for not allowing players to pause their SMD
Fix Bomber, Readme, and Description
Readme: Clarify that changes are up for discussion
Revert mongoose and tempest changes

These are now listed as under consideration, instead of changes to be made.

Update readme
Simple lua syntax checker using Travis CI

+ Tiny syntax fixes.
Add Travis Syntax Checker status
Cached DiskGetFileInfo to reduce disk i/o, can cause stutter for players
with heavy platter disk load
Removed trailing spaces

Conflicts:
	lua/aibrain.lua
Score accumulation on sim side now uses 1 thread instead of 3
Cleanup
Pause music when volume is 0

Music was played in background even when volume was 0, this resulted in
30kb / s constant diskreads which can cause stutter if a platter-disk is already
under heavy load (torrents etc)
Music fix
Optimized build range ring on selection of ENGINEER units
Optimized filtering of factories in rallypoint beat function
Fixed error with oldDiskGetFileInfo (rebase this)
Selection Range Overlay now only works for single units

See issue #94
Fixed linting
