Update to 0.69

* Convert to use GTK 3 to fix build

Changelog:
These features are new in 0.69 (released 2017-04-29):

    Security fix: the Windows PuTTY binaries should no longer be vulnerable to \ 
hijacking by specially named DLLs in the same directory, even the names we \ 
missed when we thought we'd fixed this in 0.68. See vuln-indirect-dll-hijack-2.
    Windows PuTTY should work with MIT Kerberos again, after our DLL hijacking \ 
defences broke it.
    Jump lists should now appear again on the PuTTY shortcut in the Windows \ 
Start Menu.
    You can now explicitly configure SSH terminal mode settings not to be sent \ 
to the server, if your server objects to them.
