Default values were mising for soem settings. Also added new map config settings, including the most frequently requested thing on forums: all mobs gil drop, which is a reimplementation of the global gil multiplier Compmike19 shared ages ago.

Also included new and modified existing settings to allow stronger NMs without effecting normal mobs.

  nm_hp_multiplier: 2.0
  mob_hp_multiplier: 1.0

 Will result in all NM's having double HP, but other mobs are normal.

Everything behaves retail by default, as always.

I have omitted my mod that allows subjobs to be a different fraction from retails half of main, because enabling sj abilities from levels above 49 requires additional edits (ability scripts mainly) that I'm not sure would be welcome, and we prolly don't want people to complain thing X "doesn't work" when it is only because their server is doing something custom.
Changed default value for 2005 harvest festival, because it is in dire need of updating and when enabled it crashes servers at the stroke of midnight when the date changes to October 20th.
Merge pull request #540 from TeoTwawki/misc2

Missingd efaults for soem conf settings, a few new conf additions, and set the server crashing harvest festival to default disabled.
