Implement more WMA operators

[axkr]

Implement more WMA operators from the Mathics tables named-characters.yml, operators.yml:

• https://github.com/Mathics3/mathics-scanner/tree/master/mathics_scanner/data

[X ] start with the matheclipse-parser Maven module
[ ] create a WMAParser which support all of the old Parser specialities
[] Make the @Disabled JUnit tests in WMAParserTestCase work

• [] especially the Pattern tokens handling should work as in the old parser (tests fail for example for Colon) and don't depend on the operator tables:
