New version, with much faster SVM out

Thanks to Jenny Barry, a new version of CRM114 is now 
available, with a much faster O(n) (rather than the old 
O(n^2) SVM.  There are a few bugfixes as well.  

Upgrade to this version ONLY if SVM speed is critical to
you _and_ you don't mind an incompatible file change.

Here's the blurb.  - Bill

 We now have a new SVM algorithm in place.  This algorithm uses
 Thorsten Joachims' structural SVM to achieve O(n) runtimes in
 the solver, and can solve 10,000 examples in about 5 minutes
 (assuming you APPEND them all and then do one FROMSTART).  It
 also does incremental training if you do _not_ specify FROMSTART
 (as before, APPEND doesn't run the solver, it assumes you will
 be adding more examples before needing to classify).
 
 As we're shifting to the new libcrm114 style of one-file-many-classes,
 the calling sequence for SVM (and _only_ SVM) has changed; instead of
 the previous many-file situation, you specify ONE file for both
 positive and negative examples (you learn negative examples with
 the REFUTE flag - there is now an ERASE flag to forget things).
 
 For a (screamingly fast) demo of the SVM, run (and read) the
 alternating_example_svm.crm demo file, which shows using APPEND
 and the new single-file-many-classes format.
 
 Naturally, old SVM files (both the data files and the "versus" file)
 are utterly incompatible and you will get nothing but ridicule
 if you try to use them here.
