v2.0.2 RC#3

- fixed crashes and save corruption with 'Scanf()' entry in log - caused
by faulty xr_help_wounded.script (restored script version from AI_T
v2.0)

- fixed game freezing when attempting to travel with NPC squad to one of
the new smart_terrains - NPCs will now refuse to take player there

- re-enabled 'squad targeting' in a-life - restored older version of
xr_reach_task.script:

* hunter squads can now select predatory mutant squads and run to them
instead of only traveling thru smart_terrains
* assault and elite squads of faction can do the same with lower-ranked
squads of enemy factions
* monolith can select all enemy squads traveling nearby their bases and
perform 'active defence' this way

- NPCs now see thru transparent objects slightly better

- all high-caliber sniper rifles now use new, stronger 'scripted recoil'
pattern previously used for SKS

- tweaked SKS in few aspects:

* now uses lighter 'scripted recoil' pattern
* regular SKS can mount silencer
* fixed mounted ACOG scope icon position in inventory

- vanilla "hand_radio" item sometime found in NPCs inventory now has a
proper icon, description and properties (uses uses settings of
'Mapmaking kit')
