[TYPO3-mvc] sys_category in own extension not working after 6.2 upgrade

Hi Jan,

Since 6.2, it is possible to have multiple categories fields for a given 
table. Hence we now also make use of the column "fieldname" in the 
"sys_category_record_mm" table. When upgrading from 6.1, they will be 
empty, hence the BE does not find relations anymore.

So you should just run an UPDATE statement in SQL to fill all the 
"fieldname" columns with "categories" (the name of the field). You 
should also ideally adapt your extension to take this into account, in 
case someone adds an extra category field to one of your tables.

Cheers
