Tagging 5.0.0
Updating Readme
Fixing version in main plugin file
Merge branch 'equestrian' of github.com:mtekk/Breadcrumb-NavXT into equestrian
Switch to using isset rather than array_key_exists where we can, since isset is 2x as fast
Check the existance of the options key incase people add in taxonomies late in the game... Fixes #53
On second thought, this is not the place to check for the existance of an option, we should have already found them.
