Set ruby-version to just "2.1.0"
Secure connection to rubygems.org
Amend travis config to run build matrix rather then using build script.

This is a better solution then having to source rvm for our multi components tests
on Travis CI.

Travis was unable to source rvm required to switch rvm environments.
It was failing with:
Unknown ruby string (do not know how to handle): ruby-2.1.0.

Conflicts:
	.travis.yml
Ignore all sqlite files
Fix tests. Update Rails to 4.1.6

For some reason removing the following line broke all tests of engines using other engine's migrations. schema.rb only contains migrations of the current engine. So we are putting it back!

bundle exec rake db:create db:migrate
Upgrade capybara to 2.4.1
