Compatibility update with the new version of Weapon Skin Replacer.

Improved mod description and instructions in XComUnderbarrel.ini. Fixed a bug that allowed Extra UBGL Ammo utility items to be launched through normal grenade launcher.

Localization fix for UBS Ammo Secondary.

Added secondary weapon UBS Ammo item.

It's now possible to add UB attachments to a weapon one at a time, and use different positioning for each individual attachment. XComUnderbarrel.ini and XComWeaponSkinReplacer.ini have been updated with relevant info.

Same visualization fix for UBS reload.

Fixed visualization of UBGL reload so the soldier doesn't twist their torso so much.

Added support for Richard's 'Sapper' ability (+2 damage with secondary weapons).

According to a patron request, I have added the option to make Beam Underbarrel Launchers use the same targeting logic as Blaster Launchers, as well as add an Elerium Core cost to them.

UB attachments now have a configurable Aim penalty. Keep in mind it affects UB attachments themselves as well. Zero by default.
