database: make it work with utf8mb4 

Going forward, BOINC databases should use char encoding utf8mb4
and collation utf8mb4-unicode-ci.
Each char can then be up to 4 bytes.
MariaDB/InnoDB has a limit of 767 bytes on index keys.
That means a limit of 191 chars on indexed fields.
Change the size of such fields from 255 to 191
(in some cases less, where indices involve other fields too).

create_project: use utf8mb4.

This change does not affect existing projects.
