Add all the fields to the first step on proposal creation

[microstudi]

The newly created "Reporting Proposals" component should have only 3 steps. The first step should incorporate all necessary fields before comparization.

• Add the new fields to the first step view
• Process all the fields in the firs step (probably override CreateProposal command)
• Ensure if uploads are saved before comparing
• Ensure the publish step publishes everything uploaded in the first step
• Add a "default zoom level" as a setting for the component

depends on #3
