Summary description: Bugfix release

Announcement text: 
----------------------------------------------------------------------
This release is a bugfix release.

Robert N\"{u}rnberg reported two problems in ionumbers
v0.2.1-alpha:
1. compilation of code like $a^0$ or $\sqrt 2$ will fail, if
the digit (or sign/point/comma) is not grouped in curly braces
2. the \operatorname macro of amsmath/amsopn leads to an
error in combination with ionumbers

In the current release (v0.2.3-alpha) the following fixes
are included:
1. by adding a special handling of the first character of a
number an ungrouped single digit or sign will no longer lead
to a failure (similar to the ziffer.sty package, point and
comma will still lead to a failure in these (rare) cases
from the examples above; this is documented) 
2. a warning message is added for the case that
amsmath/amsopn is loaded; as a workaround the ionumbers
package should be loaded as last package (as already
suggested) and the \operatorname macro should be used in
\ionumbersoff (this is documented); this problem is a result
of amsopn's strategy of saving the standard mathcode of "-"
and can hardly be fixed in ionumbers (amsopn together with
ziffer.sty leads to the same error)
3. the ionumbers_test file contains a lot of different input
with the output and expected output of ionumbers for
different package options; this makes it easier to test
ionumbers especially after changes

Thanks a lot to Robert for his bug reports!
