resolve_before_precompile option

[SergeyKishenin]

A configuration option for BowerRails was added that invokes rake bower:install and rake bower:resolve tasks before assets precompilation.

Rake::Task['assets:precompile'].enhance ['bower:install', 'bower:resolve'] feature should be optional as it can break deploy process sometimes. Or it can be done manually.

So I find this solution the most optimal and it can be merged if you agree. @rharriso, @jimpo, @romanenko

I agree, that reinstallation must be optional: it can take a long time to complete. Another reason is that some people keep folder with bower assets in .gitignore, so it is a must for them to reinstall assets on every deploy.

+1 for merge.

Hey @SergeyKishenin I'm on 0.6.1 and I put the BowerRails.configure... block in config/initializer/bower_rails.rb inside my app. It says no method configure for BowerRails module. Seeing that you have class << self I don't see you've done anything wrong, so you know what's causing the class not to be defined? Or am I supposed to put the block somewhere else?

Hey, @kenips. This feature is not released yet. Try the edge version gem 'bower-rails', github: '42dev/bower-rails
