Subject: [PATCH] getRemote file function added

Firstly, avoid establishing a full path if we have a getRemoteFile
action as it will be a URL
If we want to get a remote URL, attempt to get remote contents,
standardise all line endings to be Linux based, create a new tab, new
textarea and finally set the value of the new tab. If we don't manage to
get the file, show an error message
