#26 Improved ClearCase dynamic view support

[Tobias Mieth]

As i have already suggest in my yesterdays comment, the current (1.9.10) ClearCaseDynamic.pm has some issues.

1.) getDiff() in ClearCaseDynamic.pm should use CodeStriker::isWindows()
in order to determine if its running on windows, because CtCmd::setview
doesn't work on windows (see retrieve() on how it is done there)

2.) if only one tag is specified the getDiff() method should not return a
diff to the elements predecessor instead it should pull the entire element
from clearcase (this guarantees the same behaviour as in the Subversion.pm for
example)

Therefore i have slightly adjusted the ClearCaseDynamic.pm file and added support for retrieval by a single tag and fixed that path issue.
