Field calculator in SEXTANTE is very simple calculator based on
Python eval() function. So it allows only basic math with native
data types and some string operations (like concatenation).
Seems we need to improve it and add QgsExpression support.
BTW, there is also Advanced Field Calculator that should allow
calculate area and perform much more complex calculations
