made eva2 project kind of work

- "kind of" because db connection with maria-db doesn't work to zalf
mysql server, probably because it's too old (connection to climate data
server in Dresden works)
- maria-db (libmariadb.lib/.dll) is used as client lib because it can be
used as an drop in replacement for libmysql.lib/.dll
- maria-db seams to work (neglecting the above problem with zalf mysql)
while current connector/c from mysql crashes on start - maybe can be
fixed but would probably need time
