Fix #5 "Prevents text selection in console" on version >= 4149, since…

… it supports "Mousemap contexts": sublimehq/sublime_text#105 (comment)

This package was made as a workaround for missing mousmap contexts. Now that they have been implemeted in core, the package itself isn't needed anymore, so instead of trying to fix this problem, I'd rather like to know why you are running into this problem in the first place (i.e. using this package) and whether you can get rid of this package.

That said, I do understand that some old packages may still be indirectly using this package and as a way to ease the migration, I am inclined to merge this PR regardless but I also definitely want to update the readme to indicate that this package is redundant nowadays.

[FichteFoll]

This is a breaking API change that I cannot merge without a path for migration. However, considering my previous message of phasing out this package, we won't need one.

Hi, sorry for the late reply.
I am new to SublimeText, so it took a while for me to figure out what you've said.
I used SidebarHoverToggle which depends MouseEventListener. I didn't know that we can detect 'click on gutter' without MouseEventListener.
Apparently, it was not needed as you your code here just listens to 'on_text_command'.

And I didn't mean to include the second commit 'Expose click-event-arguments to on_post_mouse_down' in this pull request. I was just doing some development on my 'master' branch. Sorry, I am also new to github :D
