Release - v1.5.0

In this release I added two fraction capabilities. The first, is you can add a fraction in the input and it will convert it to a decimal and add that to the stack. For example, instead of adding 0.03125 onto the stack, you can simply type 1/32.

Secondly, you can get a fractional display of any number with the frac command. This will display a (reduced) fraction based on the denominator provided. The default is 64 which corresponds to 1/64th.

I'm sure there will be tweaks that will be needed, but so far it seems to be working quite well.
