allow multiple files to be directly mentioned in OCL

[swaroopar]

Currently OCL supports only file in 'deployer'. We must change this to allow multiple files.

• change deployer field to a Map - key must be file name (with correct file extension) and value must be the file content.
• change deployment module to directly create files with the names from the OCL instead of the fixed names.
• Test if the scripts can contain for example a shell script, a python script.
• Update samples.
