Igniter installer

[crbelaus]

This pull request adds a mix error_tracker.install task that installs the error tracker using Igniter. This task automates the installation and configuration steps detailed in the Getting Started guide by:

1. Adding ErrorTracker as a dependency
2. Updating config.exs to configure the ErrorTracker application
3. Create a new DB migration to set up the ErrorTracker tables
4. Update the router.ex file to mount the ErrorTracker dashboard

Here is the output mix igniter.install error_tracker in a project named wadus

This task can be used in two ways:

1. If you already have an existing Phoenix project run mix igniter.install error_tracker
   Take a look at the mix igniter.install docs
2. If you are creating a new Phoenix project run mix igniter.new app_name --install error_tracker --with phx.new
   Take a look at the mix igniter.new docs

I want to add a few tests to ensure that we don't break this in the future before removing the draft state.
