Void 6-11-2019 (Talksprites, Blocking, and Bugfixes)

This update should have some noticeable changes for anyone that played the previous versions; all of the placeholder talksprite assets have been replaced with custom art, the escort mission with Ethan has been revised, and blocking actually prevents damage now.

• Generic NPC talksprite art has replaced the previous placeholders to keep everything uniform.
• Ethan has a new talksprite.
• Amelia has a new talksprite.
• Ethan's rescue mission now has proper death/failure mechanics, with Ranger dialogue pertaining to it.
• Blocking now provides invincibility to attacks; this is a baby-step towards getting it fully working, but at least it has a functional use now.
• Some other small tweaks and revisions.

See you next update!
