01/23/23 - New Feats and Miscellaneous Updates

Added the Last Stand and Defiant Stand feat chains. These feats make characters more durable (Last Stand) or more dangerous (Defiant Stand) when severely bloodied.

Added the Conditions page with brief descriptions of non-core conditions, such as Bloodied, for reference.

Updated the descriptions of weapon slots for STs to make it clear which weapons can be installed where.

Tweaked the effects of some tinker gadgets that were either too useful or not useful enough.
