Implemented working igniter generation for webrick-like Rails applications. More in details.

* Implemented fully supported configure/ start hooks generation for Rails web application (currently only for Postgres). It's 1st real PoC deployment mechanism. It will require some more love later.
* Bundler will now use stage postfixed cache directory for gems.
* Changed order of execution of deployer steps.
* Using file cache for cacert gathering process (++deploy_speed)
* Automatically launch database service before doing database-specific actions of deploy process.
* Launching web worker through igniter instead of through deployer.
* Added filtering of forbidden dependencies (those which shouldn't be spawned as standalone service dependency)
* Passing branch to createEnvironmentFiles()
