Create new bill

Only ui and features, not storing to database. No backend routes done.
I can take suggestion for UI, but I will not make any kind of improvement on that matter except for real issues. 
This is focused on features : 3.2.1, 3.2.2, 3.2.3, 3.2.4 of the SRS

The table will take only the width it needs instead of `width: 100%`
