Draft mode editing for front-end campaign submission

There are several changes here I am proposing for campaigns that are in Draft mode (i.e. the user clicked Save and Preview instead of Submit Campaign). My feeling is that when campaigns are in Draft mode, the editing of the campaign should be much closer to the initial creation stage. The changes I am proposing: 

1. Show non-editable fields. If someone has a typo in their title or an extra zero in their goal amount, they should still be able to change this. 
2. Conversely, fields that are only displayed when in edit mode should not be visible at this stage yet; such as the Updates field.  
3. Both buttons at the end should still be visible; either to Save and Preview again, or Submit.

Cheers, 
Eric
