layer=0,5 gives "layer should be between -5 and 5"

[mkoniecz]

What steps will reproduce the problem?

1. create a way
2. add layer=0,5
3. run validator

What is the expected result?

"layer should be an integer between -5 and 5" or "layer should be an integer"

What happens instead?

"layer should be between -5 and 5" for value that is between -5 and 5, likely to confuse less experienced editors
