Fixed config typo that broke the rank 8 for the base game psionic medic rank.

Big update, primarily to make the mod more friendly to non-Amalgamation users.

• New set of rank icons: the base game icons in color, going from cool blue at squaddie rank, getting warmer at higher ranks. This is now the default set.
  
• Previously, non-Amalgamation classes needed to be manually set in the overrides, now they are handled by a default global change (that can still be overriden). There is also a setting to change it back to the old way.
  
• Created general settings so that changing a bunch of classes can be done with one change. For example, there is a default psi icon set, changing that setting will change all of the (psi) classes/specs that are configured to use it. (All of the existing entries in the mod have been changed to use these defaults.)
  
• Medic flags can be enabled by class, not just by Amalgamation spec. Currently only set to base game and Long War specialist classes.
  
• Auto-detection of Sparks and Proficiency classes, with different default sets for each.

Added default sets for newer spec releases.

• Added a few of the newer specs to the default settings
  
• Created medic versions of the base game and base game psi icons
  
• Turned off the default setting to log every class that was changed (whoops! this was accidentally left on in the previous upload)
