Automatically normalize pasted file or folder paths when prefixed with @

[wpenistone]

e.g.
user pastes in C:\Users\DC-FBI-FO-372\THEMIS\
adds @ to the start @C:\Users\DC-FBI-FO-372\THEMIS\
system should detect it’s a local path and automatically convert to the proper relative format (@/../THEMIS), using the same logic that handles other file mention paths.
(or it might be "@C:\Users\DC-FBI-FO-372\THEMIS\" due to how paths are copied.)
