Implemented text file upload to the server and rendering of templates.
Removed indentation on here-docs markers
(http://tldp.org/LDP/abs/html/here-docs.html) to prevent it from
breaking the generated script. The regex is set so that it only
looks for a line that starts and finishes with EOF.

This post gave me the hint
http://www.krenger.ch/blog/bash-here-document-at-line-n-delimited-by-end-of-file-wanted-eof/
Replaced indendation space with a tab since here-docs can only remove
trailing tabs at the beginning of strings.
Fixed comment on render
Refactored put to work better
Revert IFS change afterwards
