Resolve "Add the proposal session name"

Closes #52 (closed)

The attribute proposal is replaced by proposalname and proposalsession.

The state machine becomes

• OFF(1): nothing specified
• OFF(2): proposal name or session specified
• ON: proposal name and session specified
• STANDBY(1): proposal and sample are specified
• STANDBY(2): proposal, sample and dataset are specified (not started)
• RUNNING: proposal, sample and dataset are specified (started)
