Use Message Stack for "Budget per hour" template

User Story / Motivation / Challenge

As a ERPAL user I would like to use Message Stack (MS) to customize the templates for ERPAL "Budget per hour" email notification(s) so that MS would add the following benefits:

• More flexible and more powerful to match each site unique needs
• More tokens available
• Messages types can be concatenated with other Message types
• Easier to override, clone, export
• Pluggable architecture that supports customization and extensibility
• Seems easier to translate for multilingual sites

Assumptions

• Assumes that by Message Stack (MS) we're referring to the already existing ERPAL configuration UI at /admin/structure/messages
• Assumes this suggested new feature is related to another suggested new feature at https://www.drupal.org/node/2575283 But they could be implemented independently.

Suggested resolution

Move the settings for "Budget per hour" email notification(s) templates from /admin/erpal/projects to "Message Stack" at /admin/structure/messages



Above is a mockup to illustrate to suggested resolution

Any volunteer for a patch? We would be happy to contribute testing patch, quality assurance, documentation, and agile project management services if needed.

Notes

• Francois, notes to myself: Keywords for Drl search engine
  • Subject for budget email
    • Budget [erpal_project_budget:budget_status] in [erpal_project_budget:budget_project_title]
  • Body for budget email

    • The budget for [erpal_project_budget:budget_project_link] is [erpal_project_budget:budget_status]

      You will find the budget added to [erpal_project_budget:budget_node_link]
