Implemented Window Switch Manager

[LexiconCode]

Description

Window Switch Manager to swap windows by saying words in their title. In addition a command to restore the last minimized window.

Commands:

"window switch <windows>" -> switch to the window with the given word in its
                             title. If multiple windows have that word in
                             their title, then you can say more words in the
                             window's title to disambiguate which one you
                             mean. If you don't, the caster messaging window will be
                             foregrounded instead with info on which windows
                             are ambiguously being matched by your keywords.
"window switch refresh" -> manually reload the list of windows. Useful while
                     developing if you don't want to use the timer. Command disabled
"window switch show" -> output information about which keywords can
                            be used on their own to switch windows and which
                            require multiple words.

Commands have been renamed minimize win window minimize following the object verb model.

Motivation and Context

Motivation is to make it easy for users to switch windows by voice.

How Has This Been Tested

This is been tested on Windows 10 but should be cross-platform. The list of Windows is rebuilt every 2 seconds using a dragonfly timer updating open_windows_dictlist This allows for weighted commands rather than parsing free dictation. Testing on other systems would be beneficial as seeing if there's any impact on performance.

I get this one every two seconds (likely due to the refresh):

Traceback (most recent call last):

Thanks for testing this on Linux.

is_valid is Win32Window property for Windows only. It appears every two seconds because it refreshes grabbing all the windows and checks Windows to make sure they're valid.

The code should be able to be adjusted to check for OS in this case.

@LexiconCode I think I must have missed this PR. It looks quite useful, even for Dragon users.

Obviously you haven't worked on it in a while, but I would like to suggest updating the <windows> list in the grammar's process_begin() method instead of with an engine timer. Lists like this only need to be updated when the user starts speaking. Also avoids the above problem with Win32Window.is_valid.

[LexiconCode]

That's some great feedback, I really didn't like using an engine timer wasting cycles.

[drmfinlay]

Thanks! I'm not sure which grammar the rule is part of though.

Also, the is_valid property is not needed here, since get_all_windows() only returns valid windows. is_visible is probably sufficient.
