allow subdirectories in lich/scripts/

[robbintt]

Concept

give players some namespace to work with and the ability to use source control w/ scripts by traversing 1 subdirectory deep when searching for scripts.

Use case:

clone a git repo of scripts into the lich/scripts/ folder. Script search then traverses 1 sudirectory deep when trying to find a script.

Issues

• Problem: Priority needs resolved between the /lich/scripts/, its subdirectories, and between subdirectories.
• Solution: Main scripts path is searched last and gets priority. Subdirectory priority is alphabetical based on Ruby letter ordering rules (for characters not in english a-z). Probably inherited from ascii or unicode value.

Alternatives options:

1. give the player a simple method for specifying a directory, e.g. ;mydirectory/myscript
   • Drawback: longer, players prefer shorter directories
   • maybe alternative character for /. This creates potential filename conflicts unless the character is illegal in lich filenames.
