Umoria 5.7.12

• Bugfix in pray(): should loose mana when failing to recite a prayer.
• Add Press ? for help to the message bar on game start/load.
• Use roguelike keys by default, and remove setting option from the CLI.
• Player (row,col) and Monster (y,x) now use Coord_t for their positions.
• Use Coord_t in all functions that used y, x coordinates.
• Reorganise some game arrays and variables, placing them on an object:
  • put inventory onto Player_t
  • put treasure_list and current_treasure_id onto Game_t
• Type changes:
  • rcmove variable in memoryUpdateRecall() signature is now an uint32_t like everywhere else.
  • Change store_buy function signature type to use uint8_t, and return a bool.
  • Various other types changes.
• Typo fixes: item_sub_catory, current_askin_price.
• Various clang-format and clang-tidy updates.
• Move the Manual and FAQ to the historical directory and remove from release.
  It seems that these are very much out of date - possibly for any 5.x version - so
  it makes sense to move them back in with the rest of the historical documents.
• Various compiler fixes.
