Bug 528414 (swtWaylandLauncher) Part 1 SWT GDBus implementation.

General purpose GDBus interface for converting GDBus calls to SWT
events.

Adding SWT.OpenDocument event handler.

To verify:
1) Open child eclipse.
2) Create files:  /tmp/hi and /tmp/hithere
3) Run command:
gdbus call --session --dest org.eclipse.swt --object-path
/org/eclipse/swt --method org.eclipse.swt.FileOpen
"['/tmp/hi','/tmp/there']"

The two files 'hi' and 'hithere' open in the child eclipse.

- If you open two (or more) Eclipse instances, the most recently
  opened Eclipse will receive gdbus call.
- If you close the 2nd eclipse, the previous (first) eclipse receives
  gdbus calls again.

Future improvement:
  The most-recently *focused* eclipse should receive gdbus call.
