Added a few basic bash scripts for Ubuntu 14.04

Added a few basic bash scripts for Ubuntu 14.04 that should allow to setup and build Trillek. At least should help to see what is needed to build Trillek for anyone that try it for first time.
**prebuild.sh** grabs, install and compile all necesary dependecies.
**build.sh** should build correctly Trillek.

This file,s in the worst of the cases, could help to setup and compile Trillek taking a look of what it try to get and install.
