Add Date to Voting Suggestions and Break Lines Inside Autocomplete

These changes will affect the following:

1. Vote suggestions as displayed in the 'Bill' page will be prefixed with the date of the suggestion.
2. Lines in all autocomplete dropdowns will be broken on whitespace, resulting in multi-line entries in dropdown.
3. Removed the absolute width of the dropdown in bill page so they will be fitted to the size of the input they are attached to.

Edit: Fixes #210
