Manchester editor parser renamed to ManchesterOWLSyntaxParserImpl

This uniforms the name to the interface implemented.
This commit also adds a factory method in OWLManager for the interface,
and adds a Provider pattern for classes that need to be able to create
a default loading configuration, overriding it if necessary.

Tests updated to use the wired implementation rather than instantiating
the parser manually.

Methods added to the interface to allow strings to parse to be passed
in, and other necessities.
build failed because of import needed from javadoc
