Pasted URLs in TracLinks syntax

[anonymous]

When a user copies a URL, it would be convenient to convert it to TracLinks syntax automatically if applicable.

For example when https://trac-hacks.org/ticket/13737 is pasted, the plugin could hook into the Javascript onpaste-event and transform the text to #13737.

• Bonus: Support special URL parameter syntax like @: etc.
  • For example https://trac-hacks.org/browser/textareakeybindingsplugin/trunk/textareakeybindings/web_ui.py?rev=17665&marks=15#L2 to source:textareakeybindingsplugin/trunk/textareakeybindings/web_ui.py@17665:15#L2
  • Bonus: Add the current revision automatically if no revision was provided?
• Bonus: Support for InterWiki / InterTrac
  • for example https://trac.edgewall.org/wiki/TracLinks to t:TracLinks.
• Bonus: Support custom transformations (C:\Source\Dir\file.ext -> source:Dir/file.exe)

I left this in the diff by mistake. Other simple realms (that only require the same handling as wiki:) could be added there.
