Warlordocracy Early v6.8

Working on Linux, but I haven't included it. Still gonna playtest it more, probably release the Linux app in the next update.

Complete list of changes:

-Reworked arrays in source code to optimize for Linux compatibility.
-All filenames in media folder are now lower case for Linux compatibility.
-Merchants now only buy items one time (name then changes to "Happy Merchant").
-Pathfinding no longer gets stuck north of windows (all mobiles now, not just party).
-Setting objBlock to 2 in the scripts blocks non-party members (to keep livestock in pens, etc.).
-Stories with "Demo" at the end are locked as well as main stories in locked list ("Chapter 2" now "Chapter 2 Demo").
-Added new object only visible in editor: aiBlock (placed at gate of livestock pens mostly).
-Added new party members and scripts for Ch.2: Oakia, Minax, Shale, Dustbiter.
-Added new sprites for shelves: shelfBooks, shelfStuff, etc.
-Updated Player's Manual (species, characters section).
