Symbol and footprint library table parser fixes. 

Fix potential memory leak in both footprint and symbol library table
parsers when a duplicate library nickname entry exists.

Parse entire symbol library table before raising duplicate nickname
exception.

Improve the duplicate library table nickname error message to make
life easier for users to fix broken tables.
