Create additional rake tasks for building and shipping

[v0dro]

Currently the rake tasks inside rubex/rake_task are only meant for compiling a Rubex file inside a gem.

There should be additional rake tasks that help build Rubex files inside Rails apps (or any other framework) and even for standalone Rubex scripts.

@shaunakpp will it be possible for you to do some research on how exactly Rubex can be integrated inside web frameworks and what (if any) new functionality will be necessary for making this happen?
