Included "Mike's Arbitrary Precision Math Library" in DeskCalc (BSD style

license) and rebased the ExpressionParser from double on the MAPM data type.
Currently, the binary operators are not supported anymore, but the imprecise
calculations were getting on my nerves. I think a lot more neat functions
could now be supported, but I have not looked into it further. I also didn't
dare look closer at the C code of the library, but it seems to be well
tested. It's portable by all means, I guess even if the target platform has
8.3 char file names to hold the code... Luckily, the library inclused a C++
wrapper class for the data type (MAPM) which makes it fairly comfortable to
use and hides the ugly C stuff and messy memory management.

The result seems to be quite nice so far. Previously, I couldn't even calculate
my finances without eventually getting some rounding errors.
