Improve the init command

[koenhindriks]

Currently the init command accepts an HashMap?<String,Parameter> this makes parsing the init command rather difficult because parsing to different stages is needed.

Changing the init command to accept a Parameter would make parsing the init easier.

Using Translator.translate(parameter, ParameterMap?> could then be used to parse the parameters back to HashMap?<String,Parameter>.

Another idea is to add and use a Configuration object instead.
