Replace deprecated classes & methods with their non-deprecated equivalents.

All migrated components are from Eclipse 3.2 or earlier.
Remove more unused imports, variables, and private methods.

Remove the majority of remaining unused components. Those not removed are deliberately
left present, to maintain style or to prevent loss of public-access functionality.
Files not modified include tests, ast files, and files that are part of src_jython.
Allow a propertyTester in org.python.pydev.debug/plugin.xml to accept all objects.

While using the PyDev perspective, attempting to view a "Run As..." menu on a non-Python
file causes an error where viewing a "Run As..." again no longer shows any options for
Python files (other than "Run on server"). Error is caused by mismatched types between
files and a propertyTester, so allow the tester to accept all Objects.
