a recent update in albert launcher broke this plugin

[alperyilmaz]

Hi,
After update in albert launcher recently, this plugin stopped working.

The error message was complaining about albertv0 module not found error. I changed that line to albert but still it does not work. I'm guessing there's change in internals of how plugins work.

When I type sn, I see this message in debug log:

[debg:calculator] Muparser SetExpr exception:  Unexpected token "sn" found at position 0.
