[FR] Documentation wiki for developers

[redtide]

I know this is a LXQt toolkit only but I think it would be nice to have, for both non LXQt
developers like me using them and possible new developers, a wiki open to some specific
collaborators.

Expected Behavior

Have a wiki for any developer using this toolkit as reference/reminder

Current Behavior

Not a bug.

Possible Solution

See Expected Behavior.

Steps to Reproduce (for bugs)

Context

I'm using this toolkit (partially) to translate some applications of mine.
I wasted some hours to recall the previous work I did on which is the correct way to use them
as developer and which features are not needed/seemingly useless for my needs.

I think also new developers would find useful to have a base guide before looking deep at the CMake code to be ready to go. Plus being a wiki is not required to be complete after publication.

System Information

Irrelevant.
