behaviour of max is broken in 1.7

[Martijn Houtman]

The behaviour of max depends now on support of the databaselayer. I reported the bug as medium, but I think it should be high (I try to change it but it is not allowed). Lots of things that depend on max do not work anymore with mysql. Editwizards, images with templates and I believe also daymarks are not working well. It should be easy to include the old behaviour when the databaselayer does not support limiting of the number of records.   I can switch to SQL 2000 that does support it, but I found no support in MMBase for it (probably because it is from Microsoft).   Martijn Houtman
