Upgrade to v1.84.2, ColorButton and other functions added

[neclepsio]

Upgrade to v1.84.2.
Added ColorButton.
Copied from scorpheus fork KeyCtrlPressed, GetMouseDragDelta and ResetMouseDragDelta (but without default parameter and without *V variant).
Added KeyShiftPressed, KeyAltPressed, KeySuperPressed.

Added BeginDisabled, EndDisabled.

There should be an accompanying BeginDisabledV(disabled bool) function, because ImGuis BeginDisabled function takes optional 'disabled' argument. I personally use BeginDisabled(var_which_can_be_false), which I think is quite useful and less error prone than using 'if' before BeginDisabled and EndDisabled to start a disable group. Less error prone because a variable you use with if can change within disabled group block, thus making mismatching calls to Disabled functions.

Hello there and thank you for your patience.
Again, it may take some while until I get to this.
Since new functions are added as well, I might need extra time.
Perhaps I should request version upgrades to be dedicated PRs, though this is a separate thing to ponder...

Added BeginDisabledV.

Thank you for your patience.
I found one minor detail, and I am not convinced to include more BETA APIs. Please comment on that.

Thank you for the changes!
I prefer to avoid commented code, though I will take it as it is now.
