Automatic use of join aliases in HQL doesn't work for fetch joins

[Nicklas Nordborg]

The automatic expanding was needed due to a change in Hibernate 3.5 (see #1364). The issue was fixed in [5261], but the fix doesn't work for fetch joins. The reason is that a fetch join would be written as

SELECT smp FROM SampleData smp 
LEFT JOIN FETCH bioWell.bioPlate alj1

and the regular expression we use doesn't know about the FETCH keyword. This is most likely not a commonly encountered problem. I noticed it while working with a list page for bioplate events (#1536) and it can probably be worked around by manually coding the correct join.

This issue is conflicting with #1571 so I'll move this to 2.16.2 and will also merge back changes to the trunk immediately so I can solve the conflicts with this fresh in my mind.
