Meta API - Easy meta-table handling

The meta application programming interface allows easier manipulation of meta-tables. Currently, the interface introduces a function to modify the meta-table of any table by appending new meta-keys with new meta-values and optionally overriding old meta-keys with new meta-values. Additionally, the interface introduces a function to modify the index meta-method to allow indexing from multiple other tables and an auxiliary function to shorten the code necessary to set the call meta-method for any table.

Loading:

os.loadAPI("meta"); -- or whatever name you assigned the interface

I cannot guarantee that this interface functions correctly so I would greatly appreciate any criticism and bug reports.

Changelog:

• Tidied code
• Fixed localization
• Dumped lots of semi-colons
