EMMA early access build 2.1.5124 available

Stable build 2.1.5124 marks the beginning of v2.1 development.

FEATURE REQUESTS IMPLEMENTED:

999764 'v'/'version' command line option

The traditional -v|-version option is now accepted by all command line
tools, to help with issue submission.

977738 an option to auto-exclude empty classes

v2.1 will default to automatically excluding all classes with no methods
(javac has a flaw whereby it will emit such classes for certain code
patterns). This behavior is controlled by a new boolean property
'instr.exclude_empty_classes' that defaults to 'true'. Because such empty
classes affect class coverage, users who wish to retain their existing
coverage numbers can turn this exclusion off. Note that all other types of
coverage are unaffected.
