mariadb, percona: descriptions are identical to mysql ports'

[ryandesign (Ryan Carsten Schmidt)]

The descriptions of all the MySQL ports are identical:

$ port info --name --long_description mysql4 mysql5{,1,5,6} mariadb percona
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql4
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql5
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql51
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql55
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mysql56
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: mariadb
--
long_description: MySQL is an open-source, multi-threaded SQL database with a command syntax very similar to mSQL.
name: percona

That's not awful, except that I expected the description of mariadb to say "MariaDB is..." and for percona to say "Percona is...", and perhaps have a mention of being forks of MySQL.

In all these ports, the mention of mSQL is perhaps archaic. By now, I'd wager more people know what MySQL is than know what mSQL is.

I slipped updated descriptions into the last round of version updates. If a better description is desired suggestions would be welcome.
