Finalized fix for #797

See merge request orekit/orekit!193

Also remove Propagator.DEFAULT_LAW. Use IntertialProvider.of(Frame)
instead. See discussion on !189. Part of #586.

Anne-Laure did most of the work to add more informative messages when
root finding for event detection fails. This commit adds a few polishes.
- Added Anne-Laure Lugan as a contributor
- Updated messages to print g values to full precision.
- Made try {} as small as possible since catch() is so broad
- Fix checkstyle warnings
- Add test to check message is formatted correctly

Fix #685 analytic propagator null reset state

Closes #685

Fix #618 ClasspathCrawler match file name only

Closes #618

See merge request orekit/orekit!190

And also the related FieldPropagator.DEFAULT_LAW and
IntertialProvider.EME2000_ALIGNED. Left a couple usages in the tests
that were necesscessary for proper class loading and for testing the
deprecated values. #586

These methods are incorrect. They should use the default implementation
instead.

Previously a null reset state behaved as CONTINUE with analytic
propagators but not with integrated propagators. This was an
undocumented "feature". Removed it to be consistent.

Previously ClasspathCrawler matched the whole path against supported
names which caused problems with ^ as other loaders only matched the
file name. Added a test case.

Implemented for all analytic and the GlONASS propagator. The DSST and
Numerical propagator do not have a frame available in their constructor,
so the new behavior could not be implemented. Aligning the attitude
frame with the propagation frame speeds up propagation when the user
does not care about attitude and it many cases it removes a dependence
on the default data context.

Fix #586

It now has better performance when the attitude is aligned with the
propagation reference frame by avoiding multiplying by zero. With
analytic propagators using this attitude provider instead of the default
has been observed to result in a speed up of 2 in some cases, e.g. with
the TLEPropagator.
