Configuration for additional URL patterns

The pull requests adds the possibility to configure additional URL patterns that can be handled by the user defined function follow_url_func:

      -- Optional, URL patterns that can be handled by function `follow_img_func`
      url_patterns = {
	-- an arbitrary number of patterns can be provided
        url_patterns = {
          {
	    -- example for an UUID like patttern, allows to open links like
	    --   [UUID markdown](uuid://abcdef-1234-5678-90af-abcdef)
	    --   [[uuid://abcdef-1234-5678-90af-abcdef|UUID wikki]]
            name = "URL-UUID",
            pattern = "uuid://[0-9a-fA-F]+%-[0-9a-fA-F]+%-[0-9a-fA-F]+%-[0-9a-fA-F]+%-[0-9a-fA-F]+",
          },
          {
	    -- example for an app specific patttern, allows to open links like
	    --   [App markdown](app:///data/testData)
	    --   [[app:///data/testData|App wikki]]
            name = "App",
            pattern = "app:///data/[a-zA-Z]+",
          },
      },

The patterns are check in obsidian.util.is_url.

looks nice, will give it more looks once I have time, but what's up with url_patterns field inside the url_pattern?

[MaralWa]

The inner url_patterns field in the documentation is an error. I commited a fix.

Some suggestions:

1. I think you can make a new config module links (reference backlinks), and have field url_patterns. so that related features can be grouped under it in the future.
2. I personally prefer just a list of pattern strings, because you are not really using the name field in the code, and having a specific shape is friction.
