Shared Library/DLL Names for Release 2.0

[obiltschnig]

The names of shared libraries/DLLs for POCO 2.0 should use the Poco2 prefix:

• libPoco2Foundation.so.n / Poco2Foundation.dll
• libPoco2XML.so.n / Poco2XML.dll
• etc.

Rationale: We can restart the shared library version number at 1, instead of 100 (and hope that 1.x releases won't catch up...).
