Bump version number to 1.2.11
Manually set columns to select.

Now, this is the Orm\Builder that specifies the columns to select.
We do not try to guess what user wanted with _onAfterBuild(). However,
_onAfterBuild() is still used to easily set the "from" component. It
might be used in other builders too.
Merge branch 'hf-1.2.11'
