* Random accumulated tweaks and fixes.

- Added a error message to npc_enable, to spot disablenpc/enablenpc/hideoffnpc/hideonnpc on non-existing NPCs (related r14750).
- Replaced inlined npc_name2id code with calls to npc_name2id.
- Open Buying Store skill is now exempted from noskill mapflag like Vending as well (bugreport:4815, follow up to r14713).
- Fixed signed constant being returned as unsigned value in get_percentage (bugreport:4765, since r12679).
- Replaced strlen checks, which checked whether or not a string is empty, with first-byte checks.
- Fixed enabling 'fakename' not clearing party and guild name and cleaned up atcommand 'fakename' code.
- Cleaned up party/guild name code in clif_charnameack (follow up to r14737).
