Location Explain 1.0.2

fix for XF 2.3 compatibility

The account_details template changed in v2.2.8 (as a result of this bugfix notification: https://xenforo.com/community/threads/location-field-is-not-marked-as-required.199852/) which in turn broke the template modification for this addon.

v1.0.1 updates the template modification to work with the new version of the template and sets the minimum required version of XF to 2.2.8
