Version 1.64 WIP

Version 1.63

Internals: Tidying up, moving helpers to imgui_internal.h (in prevision of 1.64 refactor)

ColorEdit4: Fixed a bug when text input or drag and drop leading to unsaturated HSL values would erroneously alter the resulting color. (#2050)

Internals: Merged some changes to facilitate 1D->2D transition for some elements, and merging the stack layout PR (#846)

Internals: Renaming of non-user facing parts from ValueChanged to Edited terminology. (#2034, #820, #956, #1875)

Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete fast as IsItemDeactivatedAfterChange() is very recent). (#820, #956, #1875, #2034)
