colors starting with 0E break output formatting

[timohausmann]

Hey, I noticed with output formatting active, #0E1779 becomes #000000.

Must be this line and some funny php behaviour.

var_dump("0E1779" == "0"); // bool(true)

I guess PHP interprets the color as 0e1779 (scientific notation), becoming 0.
Strict comparison === fixes this.

Edit: I'm not really sure what this line does to begin with. I only see it "trigger" when I configure a Default Value "0".
