SPIMAcquisition: Added AcqRow reordering

By request, I've added the ability to reorder AcqRows, letting users
create them in any order and then put them into a more sensible one (i.e.
so the twister doesn't have to go back and forth a few times over the
course of a timepoint).

squash! SPIMAcquisition: Improvements to GenericRotator

More of a fixup, really, but I wanted to reword, so.

SPIMAcquisition: Go-To button, behavior refactored

By request, I've added a button to send the stage to the selected row. I
should note that this behavior is already present by double-clicking a
row, but we don't really specify that anywhere; it wouldn't hurt much to
have this button on the side.

SPIMAcquisition: Update Live by default; move Home

By request, Update Live View has become the default setting. For most
purposes having it on shouldn't slow the system down considerably; if it
is found to, the checkbox is still there. I also moved the Home button to
sit beneath the three linear stages, since those are the only ones it
affects -- its counterpart, the Set Zero button for the twister, sits
beneath its stage as well.

SPIMAcquisition: UI Underhaul

The changes won't be very visible to users; the most noticable will be the
new 'sweep' button on the position list, which inserts a continuous stack.
A few buttons have been moved around as well.

Basically, initUI was getting totally out of hand, so I broke it up into
smaller methods; this should make it more navigible (in particular within
an IDE).

SPIMAcquisition: Add Easy Stack

By request, I have added an 'easy-stack' feature, which lets the user mark
the beginning and end of a stack from the stage controls window. Although
it pulls us away from hyperrectangular data like we would like, the
feature should make setting up acquisitions much easier.
