There are some reserved words in Java which need to be forbidden for column names

[ldhasson]

We had a tale with a column named "class", So the code generated included the method getClass() which overrides the base method from java.lang.Object. The method returns a Class object and so the method clashes and won't compile.

Currently, getClass() is the only method that can create such a clash, so it's a very easy thing to fix in Tilda.
