e-util: Port to thread-safe ECategories API

This ports the following two function calls throughout Evolution:
 • e_categories_get_list() to e_categories_dup_list()
 • e_categories_get_icon_file_for() to e_categories_dup_icon_file_for()

It necessarily changes some internal e-util API:
 • e_util_get_searchable_categories() to
   e_util_dup_searchable_categories()

This bumps the EDS requirement to 3.13.1.

Thanks. Please fix "the one" thing below and commit to master.

 	for (iter = list; iter != NULL; iter = iter->next) {

Please do not write the /* owner */ comment, it's understood from the fact that the string variable is defined as non-const. Remove the comment from the whole set of changes.

Pushed to master with the changes requested above. Thanks for the fast review!
