We needn't check the pointers here as `loadRun` would have thrown an
exception on failure.

There are some methods we just don't care about, so let's not bother
setting expectations and just provide stub implementations.

* Rename fake workspaces to fake run numbers
* Get rid of superfluous assertions

This new helper function can created fake workspaces to use for
processing in the tests, instead of loading runs like INTER1346{0,2,3,4}
from disk.

It won't play nicely with the coming changes. Autofill will probably
need to be moved to its own action for better testing in future.

It brings the unit test time down to an acceptable place.

The lists are small so traversal time is not an issue but it is
quicker to push back to a list.

When called millions of times in a loop, e.g. Monte Carlo, then this can
make a noticeably difference.

Now that we are not rounding by default, the expected values for unit
testing need to be updated.

It has no advantage over the "Ok" button. The dialog forces itself to
remain in the foreground, so nothing can happen between the user hitting
"Apply" and closing the dialog. We may as well be tidy and remove it.

Use the `reflOptionName` property on a widget to specify the option its
value should control.

Users may now individually specify what level of rounding is applied to
the angle, qmin, qmax, and resolution columns.

Instead of manually having to load/save options to/from widgets in
QtReflOptionsDialog, we now load/save options using a map binding
options to widgets. It may seem overkill for just one option, but when
we have fifteen to twenty it'll greatly simplify our life.

It could be expanded in future to build the bindings from widget
properties in the UI file, so new options need not even touch
QtReflOptionsDialog's code.

Use STL algorithms for value searching and static storage for
constant arrays.

The main algorithm code is easier to read this way.
