Fixed bug where addon uploaded no content when used on Release.
Note that if you want HTML to markdown conversion in release Firefox you can flip the `dom.events.asyncClipboard.clipboardItem` pref to true in `about:config`

You can now replace patterns in the repo path with date components

"%YYYY" - year
"%MM" - month
"%DD" - day
"%HH" - hour
"%mm" - minute
"%ss" - second
"%sss" - millisecond

Added turndown rule to handle nested lists better.

Added conversion to markdown from HTML
(Only works on Nightly due to https://caniuse.com/mdn-api_clipboarditem - fallback to text when API is not available).

Fixed an issue where uploading a text containing unicode characters (non-ascii) failed.
See https://github.com/valenting/clip_to_gh/commit/81e18928032ab286f9db4c26e8c138f3a4f33fc5 for fix.
