[BUG] Custom "Command" type doesn't allow negative values

[puterboy]

I am using TopTemp to display the outside temperature which in the Northeast U.S. is now negative in Celsius.
This causes an error since it seems that command is expected to be a positive number.
There are other sensors which could presumably give a negative number too.

Strange - hmmm will need to test

Should be fixed now: https://github.com/LazeMSS/OctoPrint-TopTemp/releases/tag/0.0.2.1

I think there is still a bug here. The 'test' now works (per your code fix) but it still won't display a negative number -- it just gives a spinning wheel...

OK - I found the problem.
Try this fix:

Only limitation here is that '--2.3' (or any number of initial dashes) would be recognized as a number.
If you want to eliminate that case you would need to either add more logic or use 're' for regex test.
