Bug 525305 – [API]Provide SWT.OpenUrl event (Linux implementation)

(For review/merge)

Linux implementation for OpenUrl event, with use of GDBus.
(As per original patch *1).

URL vs file detection done via "new URI(file).getScheme()".
I tested, this distinguishes URI's from files quite well.

I.e:
  /myfile/  ./file  file  .. ->  (OpenFile)
  http://www.eclipse.org   mailto:my@mail.com  ..  -> (OpenUrl)

I've tested with latest launcher:
1) Via launcher:
eclipse http://www.eclipse.org /tmp/myFile

2) Via gdbus calls:
gdbus call --session --dest org.eclipse.swt --object-path
/org/eclipse/swt --method org.eclipse.swt.FileOpen
"['http://www.google.com', '/tmp/myFile']"

Patchset 2:
- Updated URL detection logic so that files/urls are properly
distinguished.
