v0.7.0.2.0

Changes:

- fully integrated 'Update 15' by N.Aaroe (fixed by Ponney and me)

- fixed radios music pathing

- fixed Heavy Coat icon

- revamped descriptions for all quest items to make them fit into new
system

- fixed item prices and statistics for all 3 classes

- implemented 'damaged' scope models by N.Aaroe. Damaged scopes are now
default ones for all 'rusty' and 'worn' weapon profiles - NPCs with
those guns will have such scopes on them

- tweaked description of UPD to have common item indicator and show
battery icons as ammo (UPD capacity needs to be a full number - set to 3
Ah)

- tweaked knife descriptions to show knife icon instead of ammo

- made numerous small UI and text fixes and tweaks

Balance:

- made higher grade suits and helmets significantly more expensive to
purchase (this does not affect repair costs)

- made destroyed much less valuable for 'junk' traders

- fixed other stalkers pricing so that they pay less for anything than
base traders

- properly balanced scientistcs pricing policies

- rebalanced granades to be more deadly. Shifted damage of nades much
more towards multiple fragments, slower but deadly at greater range
