WP 34S and 31S bugs and fixes

[Bit]

1. Incomplete or invalid fractions cause delayed error messages ...
2. CLx produces domain error if the command line contains a bad fraction ...
3. EEX not allowed in fractions mode even if no fraction was entered ...
   

I've committed patches that fix issues 1 and 2.

I've also added a compile time option (IGNORE_INVALID_FRACTIONS) that disables command line checks and causes the calculator to simply ignore invalid fractions: a.b.0 becomes the integer a and a..0 (if such fractions are enabled) becomes zero. It saves ~ 252 bytes in the 34S, and considering that invalid fractions never appear automatically or in any non-obvious way, some may prefer not to spend that much firmware space only to report that one error condition.

Please test and report any issues or weird behavior.
