PicoCalc Updated to 1.0.1

Three unfortunate bugs made it into the first public release. These are repaired.

• Very dumb "save" bug prevented work from being saved. (debugging file got put into the public release by mistake)
• @or function wasn't working. Long story short, due to token count limit its scope had to be limited to a 2-item comparison, rather than a list of items. This now works for 2 items. You can also chain this together such as @or(@or(@or(a1,b1),c1),d1) to get a longer set of comparisons
• @and function had the same problem as @or above. This is now repaired.
