Generic Launch ConfigPage for path mappings

[Niko Sams]

Hello,

Every (potentially) remote debugger needs a way to map local paths to
remote paths. That
includes even gdb if we would support remote debugging.
To get this running the user needs to configure those mappings, as I
have already implemented
in xdebug. Now I need exactly the same ConfigPage for Crossfire
(another debugger plugin) and
would prefer not to copy it.
Speaks anything against moving it to say
kdevplatform/debugger/util/pathmappingwidget.h/cpp?
