Update spanish translation with event creation warning
Remove Column Chooser from Chart Settings

Because the chart settings are modal its a really bad
idea to open up a column chooser from there. So, by
default, we don't have a column chooser option on the
search/filter box -- it must be explicitly requested.

We therefore explicity set the column chooser from the
mainwindow and also from the ride navigator window.
