Removing travis

Removing travis because it never works
Removing Asset install from composer

Removed the calls to cache:clear and assets:install from the composer
install and update scripts.

These calls are duplicated by the phing task and will fail without
the files generated by the build script
Adding composer local file to install script

Changed the if statement to load composer from local file if it exists,
If it doesn't it tries a path executable
Reverting config file to skeleton so it does not change on composer install
