Part one of this contribution is a bugfix. The decimal precision of STEEMP was changed from 3 digits to 8. In several places, withdrawing for example, the precision of the STEEM amount in the transaction was still rounded to 3 decimal digits. This caused problems when the amount was rounded up and and exceeded the users balance.
I fixed the rounding so that it always floors the amount.
The second pull request contains some more style improvements for smaller screens.
And the table on the balances page is now also scrollable.
So now that's it. @beggars is working on the new UI and I'm happy with the current one.
