SqlElement::getTitle() should return i18n('col'.ucfirst($col))

Hi,

Before:
public function getTitle($col) {
return i18n('col'.$col);
}
After:
public function getTitle($col) {
return i18n('col'.ucfirst($col));
}

See the difference by moving your mouse over environment lists on TestCase, for example.
Before: [colidContext1]
After: environment

By the way, is it possible to have a specific "title" language element? I mean, use i18n('title'.ucfirst($col)) instead of i18n('col'.ucfirst($col)). Our new users doesn't know very well the application so it would be very useful to have a longer description of the field (instead of just the name) so they can see what to do with the field by moving their mouse over (without having to open the documentation every time). If it is too much work for you, maybe you can just add them for the fields with "title" attribute (I think there are only titleIdContext1, titleIdContext2, titleIdContext3). What do you think?
