Invoices: Ability to change column widths

[NRBInstall]

I have noticed that the column widths on invoices are wider than they need to be.  This includes columns: Units, Unit Price, Tax Type and Amount.  The tax type column only requires 3 characters, however it appears to be at least 10 characters wide.  If you make each column the required width, this gives us more space in the description column.\

We need to be able to adjust column widths in any list view as well. It's annoying when important details are truncated when scanning through.
