Fixed tab stop order in the Options Dialog, Connection page

[maximmasiutin]

The tab top order of "Global maximum number of upload slots:" and "Maximum number of upload slots per torrent:" was swapped. To reproduce the issue, focus "Global maximum number of upload slots" and press "Tab". Expected behavior: "Maximum number of upload slots per torrent:" should be focused. Actual behavior: focus jumps to other controls below. This pull request does not add or remove any lines, it just changes order of existing lines.

Doesn't seem to break anything although the tab stop order is already fixed in master

So what does this PR do then?

It puts the graphical controls in correct order. For example, they were 1, 3, 2, 0. Now they are 0, 1, 2, 3.

PR title says that it fixes tab stop order but @thalieht says that tab stop order is already correct. So I'm confused...

Any GUI changes should have screenshots......before & after.

[maximmasiutin]

These are not the GUI changes. The visible order of the controls is the same, it is only the tab order changes. I can make the screenshots but they are identical.

This PR is going the right direction. It can correctly specify tab order without explicit <tabstops>.
However, there are more wrong order instances in optionsdialog.ui (and possibly other .ui files). It would be best to change them all in one or two PR.
