(Feature) Transfer tokens

[vbaranov]

Relates to #134
Built on #142 (should be merged after this PR)

The last part of tokens' management support; the ability to transfer tokens.

@dennis00010011b e2e tests are affected with this feature, could you please update e2e tests to support this feature also?

Send tokens dialog:

1. No decimals validation. There is should be any error message like ' ... decimals should not exceed the amount of decimals specified... ' if fractional part of amount longer than specified of decimals

2. Can not send valid amount of token with more than 16 significant digits (even if token decimals =18), button 'Next ' is non-clickable, uncaught error in console

No decimals validation. There is should be any error message like ' ... decimals should not exceed the amount of decimals specified... ' if fractional part of amount longer than specified of decimals

Could you please create an additional issue for that? For now, all extra decimals should be truncated on the confirmation page before sending transaction.

Can not send valid amount of token with more than 16 significant digits (even if token decimals =18), button 'Next ' is non-clickable, uncaught error in console

Should work now (bignumber errors were disabled for this page)

Should be const parts = input.split('.') ?

Firefox-Send tokens: no error message if amount too precise, clicking button 'Next' leads to open 'Confirm transaction' dialog

It works in Chrome:

Right, nice catch!

Could you create additional issues for FF bugs with the label FF related?
