Create mustache template node

[sverhoeven]

The configure node uses Mustache.java template to generate the config file content.

The usage of a template engine could be made in to a node.

The node should have a dialog with a text editor and input column selector, the output should be a string cell for each input row. During editing of the template should be syntax checked.
