Merged translations done by Rynbef and bakka and corrected them starting from 1 to - including - 100.
* Added some iRO Eden Group NPCs. (credits: -SkittleNugget-)
- This consists of a few traders, warpers, cashshop-related scripts, and duplicates from various locations.
- There are a lot of placeholders and some entirely missing scripts; these may be added later, but we don't intend to implement all of iRO's custom features.
- Some of the item sprites may be unviewable without iRO's data.grf.

* Minor database updates:
- Corrected all *_C (rental) equipment entries; to be updated later on with VIP bonuses.
- Fixed some bHpDrainRate item_db entries. (incl. bugreport:8049)
- Fixed a mob_skill_db entry. (bugreport:8050)

* Other changes:
- Renamed 'F_RandMes' to 'F_Rand', to clear up any confusion. (follow-up 66a2bfd)
- Small changes in Armor Enchanter script (thanks to Emistry for pointing it out :p).
