Preserve the text range after cellIn after xmlSetValue

[bvw]

Currently the textrange is collapsed to the end of the range after xmlSetValues

I think something like this would work but needs more testing:

dbRow.js:

dbCell.js:

dbEditorText.js: (all other editors would need to be updated to support new getTextRange method too)

Port this change to preserve text selection into latest qcode-ui: https://github.com/qcode-software/tlc-erp/pull/1737
