Update 0.171 Terra

Update 0.171
Nothing too crazy this update, just trying to keep consistent. 

Added two new heavy machineguns:

• Archangel HWS, with two variants; 20mm autocannon and .50cal machinegun
• Brigade .50, with five variants; heavy, aircraft, watercooled, explosive and stinger

Added one new character:

• First Recon Commando - Terra

Other changes:

• Fixed a bug that prevented elemental resistances and weaknesses from calculating
• Fixed a big that prevented weapon heat from showing
• Various first person animation improvements
• Turned texture filtering off

Enjoy!
