#2 Improve memory management

[Anonymous]

In order to improve the current "Alpha" state of the
software, I would like to submit a unified patch that
deals with some of the pointer variables in the C++
code. Some were changed to std::auto_ptr, one to
std::vector, quite a few delete's (at least one would
have been called on malloc'ated memory) were removed.
The global (sic!) skSolver's are completely removed.

Cheers,
Andreas
