In repo controller entry action, show the page for the file even if it's binary (so user still has access to history etc links). This makes it possible to use the entry action as the default when a file is clicked on

# This code lets us redefine existing Rake tasks, which is extremely

You may experience issues testing multiple plugins at once when using
the code-mixing features that the engines plugin provides. If you do
experience any problems, please test plugins individually, i.e.

  $ rake test:plugins PLUGIN=my_plugin

or use the per-type plugin test tasks:

  $ rake test:plugins:units
  $ rake test:plugins:functionals
  $ rake test:plugins:integration
  $ rake test:plugins:all
