ehnc Donation form errors

Styled errors and some more layout things. Basic responsive
working.

Decided not do do the bubble UI for error messages for this
iteration due to time constraints.

For further dev; I think Eric wanted form errors to appear
as you type in the form, which also may be too much for
this iteration.

TODO:
- js
- Bug on "business with peace corps" checkbox where label
is not linked to checkbox (even though I did correct for
attr), will figure out later.
- address cont field is showing error when main address
field has error.
Took out extra code
