implements `wsh run` command. lots of fixes (and new options) for command blocks. cleans up the UX/UI for command blocks. lots of bug fixes for blockcontrollers. other minor bug fixes.
also makes editor:* vars into settings override atoms.
New context menu options are available in the directory preview to
create and rename files and directories
It's missing three pieces of functionality, none of which are a
regression:
- Editing or creating an entry does not update the focused index. Focus
index right now is pretty dumb, it doesn't factor in the column sorting
so if you change that, the selected item will change to whatever is now
at that index. We should update this so we use the actual file name to
determine which element to focus and let the table determine which index
to then highlight given the current sorting algo
- Open in native preview should not be an option on remote connections
with the exception of WSL, where it should resolve the file in the
Windows filesystem, rather than the WSL one
- We should catch CRUD errors in the dir preview and display a popup
