v0.7 - The first Steam release — Parasite Steam update #939442

This is the first release that is available to Steam players (pre-release at the moment of writing). The major focus has been on changing the underlying platform for easier development and on making the UI prettier. all HUD and windows UI elements converted to new system with background art added; full UI mouse support finally completed; previous inventory, knowledge and body windows have been merged into one "body" window with multiple toggleable segments; bitmapped font changed to vector; many small bugfixes and tweaks due to these changes; no changes in gameplay yet;
