Insert symbols overlay (#2051)
* Add flag for enabling insert symbols feature

* Add symbols overlay directory

* Detect if :xy is inserted into editable

* Allow naive updating of overlay, and special handling of ':'

* First step towards better Virtual Element support

* Update floating to reference range on insert text

* Position SymbolsOverlay always on top or bottom

* Add a data-provider to emulate API

* Show correct suggestions in symbols overlay

* Rename to replacementLength

* Allow replacing via clicking in menu

* Optionally remove inline padding of Popover

* Hide Symbols overlay on blur of content editable

* Add specialKey to inputHandler and generalize how arrow movement is detected

- This way macOS users can use Ctrl-N to mean down, etc.

* Detect special key from within SymbolsOverlay

* Implement full backwards search while typing

* Allow navigating symbol menu and accepting with enter

* Add some entries to data-provider

* Satisfy eslint

* Generate symbolsTable from sources

* Use other github source, allow multiple names

In return, symbol must be unique

* Automatically scroll in symbols dropdown

* Use from npm packages rather than downloading from URL

* Remove console.log

* Remove print

* Add pointerDown event to input-handler

- so that SymbolsOverlay can reset on field click

* Make tab do the same as enter

* Make font a bit smaller but increase relative icon size

* Satisfy type requirement of handlerlist

* Revert changing default size of DropdownItems

* Remove some now unused code for bootstrap dropdowns
