on linux assume datapath is always relative to cmake_install_prefix, unless you provide an absolute path; on win32/osx hardcode engine path to default installation prefixes (it gets overridden at runtime so it works even if you move the data folder)

Oops, forgot this check (fixes crash)

typo and doc

fix file association on windows too

use rev info from the just created file when configuring without mercurial

dump rev and hash in a file to be packed by cpack

adjust cpack ignored files (libraries, mobile project files and win res files are still necessary)

hopefully fix bug #523, file extension association

merge for the win

caught two frontend warnings

convert HAVE_NETSERVER to check for file existance, so that it's easier to provide missing servers

convert HW_DEV in ifdef DEBUG clauses

fix portal/hammer interaction, ban freezer from portal

keep hogs from sliding while they are being frozen

Make hogs thaw only on enemy turns, make timebox counter decrement only on your turn, adjust knock for frozen hogs, increase damage on frozen hogs, make freezer fuel only reduce when not adjusting angle.
