Help+LibManual: Move non-UI-specific manual handling to LibManual

Browse source 
This is a first step in deduplicating code within and across Help and
man.

Because LibManual also doesn't contain any DeprecatedString, some
adjustments to Help's string handling is included, just to interoperate
with LibManual better. Further work in this area mostly requires String
APIs in LibGUI.
