Fixed invisible weapons

Tweaked sprites.

Fixed caps of files referenced in title_page_lapine, will hopefully help Linux users.

Fixed the "trapper" permitted job tag

-Fixed crashing when making a new world after loading a mod, had a few typos in tile coordinates for sprites

-Figured out how to add updates :P, increasing "numeric version" in info.txt under installed mods just causes the mod to no longer work, you instead have to increase numeric version in a new uninstalled version of your mod under the "dwarf fortress/ mods" folder in order for your updates to work.
