Added "Fees and limits" page

Dear users!

We added the "Fees and Limits" page to the footer of the site. The page provides up-to-date information about the minimum amounts of deposits and withdrawals, active fees, limits.

Also we remind that for security purposes we have a limit on automatic withdrawals:

- for unverified users 1 BTC in equivalent for 24 hours

- for verified users 10 BTC in equivalent for 24 hours

All withdrawals exceeding the limits will be checked by the Security Department and processed not in automatic mode, but in manual mode from 30 minutes to 12 hours.
