More zonepoints

[xscreach]

uint16 for zonepoint.position

[cloudkucooland]

are we really drawing zones with more than 128 points?

you will also need to update

Wasabee-Server/model/database.go

Line 78 in be51ddf

{"zone", `CREATE TABLE zone (ID tinyint(4) NOT NULL, opID char(40) NOT NULL, name varchar(64) NOT NULL DEFAULT 'zone', color varchar(10) NOT NULL DEFAULT 'green', PRIMARY KEY (ID,opID), KEY fk_operation_zone (opID), CONSTRAINT fk_operation_zone FOREIGN KEY (opID) REFERENCES operation (ID) ON DELETE CASCADE) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;`},

and add an upgrade for existing schema (same file, line 139)
