RDE Template Fix

Fixes RDE templates created prior to v2.7.0 to work with v2.7+.

Background

Prior to v2.7.0 colLang was the attribute used to represent language selection in RDE templates. From v2.7.0 the data model for languages was updated and colLanguage and colScript attributes are used for language & script selection in RDE templates. This plugin deletes references to colLang and inserts references to colLanguage and colScript.

To install:

1. Stop the application
2. Clone the plugin into the archivesspace/plugins directory
3. Add rde_template_fix to config.rb, ensuring to uncomment/remove the # from the front of the relevant AppConfig line. For example: AppConfig[:plugins] = ['local', 'rde_template_fix']
4. Restart the application
