IZPACK-871
Simplified registry access, so that RegistryHandler can be used in place of the oddly named RegistryDefaultHandler
implementation.
RegistryDefaultHandler now delegates to a platform specific implementation of RegistryHandler,
if registry access is supported, or a no-op implementation of RegistryHandler if it isn't.
The RegistryDefaultHandler.getInstance() method is now deprecated.
Backed out RegistryDefaultHandler changes as they were pulling in classes from the com.coi.tools.os.win package
which are not included in the uninstaller on unix platforms
Merge pull request #89 from unb/master

Backed out RegistryDefaultHandler changes, but left in minor code cleanups
Refactored PathInputPanel to allow subclasses to override aspects of path validation.
Note that some aspects of this class don't make a lot of sense:
* why does it use TargetPanel message strings?
* why does it contain the installation modification check? Surely not applicable for JDKPathPanel
