fix for "Unexpected semi-colons in conditional" issue, as reported by YuGiOhJCJ (see http://www.hedgewars.org/node/5860 ) big thanks to burp for helping to identify and fix this issue

Some further work on map optimizer

tweak untint a little (especially in connection with GrayScale)

theme configurable sudden death music. untested

allow teleporting outside Land[]

escape info message arguments, fixes issue #801: Frontend parses INFO command output as html

collision indicator on failed girder placement (especially useful with rubberband I guess). still needs some tweaks but I am going to bed now :P

disable these weaponset flags. they bug up highlander and otherwise have no useful impact on the script.

get rid of fpc warnings/hints

Fix some of issues found by coverity

Official racer challenge map #8

Inform frontend of lines which didn't change anything on the map in advanced drawn maps mode

Fix some pas2c engine warnings

Count number of pixels changed during draw

Small optimization (no need to draw last point of the path)
