Remove the table name from the query structure.

[epugh]

This PR is based on experimenting with SMUI with sqlserver and mysql databases. SQLServer specifically didn't like the table name being part of the column names. With this PR (and some tweaks to the schema) SMUI could run against SQLServer.

I thought more about it, and thought that not having the table name in the rowparser would make it easier to read.

I don't know if there are any other simplifications that could be made?

Thanks , @epugh for the PR.
It needs to be checked , if removing the table prefixes will break the test automation (hint: some JOINs are used in the EventHistory feature).

I understand , removing the table prefixes is necessary in order to have a broader DBMS support like suggested in #69 .

BTW, I did run these tests:
