Qt strangeness, object creation order in maintab.ui seems to matter.

[Michael Andreen]

Hi,

I've been playing around with some minor ui modifications, mainly adding a 
line edit to maintab.ui. However, when I edit the ui with Qt Creator it 
rearranges objects so they are not created in the top-down order they were 
before.

For some reason this makes the save and undo buttons start to misbehave, a 
double-click is required to take the right action, a single click will hide 
the message about the dive being edited, but it won't enable the dive list 
again.

If I edit ui_maintab.h manually and put the creation of the buttons at the end 
then things work again. Also reordering them manually by editing maintab.ui 
does the same thing.

I can't find anything in the subsurface code that requires this ordering, is 
it a Qt issue? This is on a mostly stable gentoo linux, with both qt 4.8.4 and 
4.8.5. Qt Creator 2.7.2 and 2.8.0.

Using Qt Designer causes less reordering, so using it seems to be a workaround 
for now.
