Matthew Barnes f267827d67 ETableSpecification: Implement GInitable. 
e_table_specification_new() now takes a table specification filename and
a GError and parses the file as part of instance creation.  If a file or
parse error occurs, e_table_specification_new() returns NULL.

This replaces e_table_specification_load_from_file().

New functions:

  e_table_specification_get_filename()

Removed functions:

  e_table_specification_load_from_file()
