Implement TCP remote control server

[Doralitze]

We need a basic remote control port. I think a line based command protocol should suffice. We might use the parser later again in order to implement a CLI. The following commands are required for now:

• list scenes Get a list of scene ids
• list filters List the filter ids in the current selected scene (Selected as in CLI context, not as in currently running)
• list columns List the columns in the current selected bank set
• list banksets List the available bank set ids
• select scene <scene-id> Switch the current selected scene to <scene-id> (default: the current active one)
• select column <column-id> Add column id to the list of selected columns
• select bankset <bank-set-id> Set the currently selected bank set to <bank-set-id> (default: the current active one)
• activate scene Set the current active scene to the selected one
• set filterparam <filter-id> <key> <value> Update the parameter of a filter within the selected scene

• bankset commit Commit the selected bank set
• bankset create Create a new bank set and make it the linked one
• bankset Display informations about the selected set
• bankset add <bank> <type> Add a column of <type> to <bank>

This is implemented with the GUI. Fish will get a protobuf based synchronization port later.
