SettingsHelper: Use I18n.t instead of deprecated Redmine::I18n.l
removed bullet&footnotes

especially footnotes takes up a lot of processing-time: If you really
want to look into the performamce of the app, move the dependencies
into your Gemfile.local
Add environment-specific seeds and load plugin-seeds

The commit adds a mechanism to load seeds that are specific for the
given environment. The seeds are stored in db/seeds/<environment>.rb
and should be written idempotent, to make sure, they don't
destroy/overwrite anything when being run multiple times.

The seeding now also loads the seeds for the plugins, which allows
plugins to add plugin-specific constants to the database.

Stop replacing links inside macros

The textile-formatter runs before the macros: If a macro uses a url as a
parameter (e.g. to
{{embed_youtube(http://www.youtube.com/watch?v=bqzQ2qrtBeg)}} then these
urls where replaced with an inline link (<a href="...") - the commit
makes sure, that urls inside macros remain untouched.

Added a sample project to the development-seed.[skip ci]

using RAILS_ENV=development rake db:seed, you can now generates a sample
project: The project contains several issues, a timeline and lots of
planning-elements to play with. Feel free to add some more sample data
to this pet-project.

The project is re-generated every time you seed the database, so every
changes to this project will be lost.

The ci is currently skipped, as it currently does not run the seeding.
