remove highlighting download dialog
Summary:
rational:
- there is one frameworks release per month that already provides a stream of hl updates
- often new highlightings anyways need a new frameworks version
- one can easily update only a part of the files which leads to broken other highlighting that include parts of them
- the updates might easily break the non-downloadable indenters
GUI: highlighting download dialog removed
Test Plan:
make
make test
