bugfixes to live service

[xsrust]

Best to look at the commits seperately for code review:

Updated display of publish/unpublish buttons

• changed logic on template index page to
  • only display 'you have unpublished changes' if the template has been modified, not just viewed
  • does not display publish or unpublish options when 'transfer customization' id displaying, as both are invalid options
• ensured that all actions on a template cause the 'dirty' flag to be set. (annotation updates and transfer/creation of customization were not setting this flag)

Updated plan creation logic to dissallow outdated customizations

• ensures that only up to date customizations of the most current funder template are given to users to create plans based off of. This will be clear from the messaging the user recieves upon plan creation, i.e. it will not say that their template has been customised.

Updated rake task to remember which annotations should be preserved

• Now remembers which annotations have already had their text de-duplicated, and excludes them from future selection
