Resolved - Add calc command to Junco code

This simply uses the Perl eval command to process an arithmetic string.

Format: calc = arithmetic expression.

After the eval is processed, the calc command is surrounded with brackets and included in the output.

(5+3) / 2
= 4

440 * .4
= 176

440 * .6
= 264

7/5
= 1.4

Here's an intentional syntax error:

5(3
= arithmetic string could not be processed. syntax error at (eval 76) line 1, near "5("

Need to work out the formatting kinks a little, but if I want a quick calculation, this will suffice.
