Redmine

Sorry if this doesn't belong here but I can't find any way to contact the current maintainer directly.

The Computed Custom Field plugin can cause internal server errors when creating/editing model objects from other plugins that do not include the `acts_as_customizable` extension. (eg. RedmineUP CRM)

I have tested the following fix to the file https://github.com/annikoff/redmine_plugin_computed_custom_field/blob/master/lib/computed_custom_field/model_patch.rb, although I'm not certain this is the best solution.
