Format decimal points not working correctly

[SylwesterZarebski]

Last revision of fatfree changes number decimals handling and accidentally broke it.
Culprit is commit #3604f7a in fatfree-core:
https://github.com/bcosca/fatfree-core/blob/master/base.php#L995
which goes to:
https://github.com/bcosca/fatfree/blob/master/lib/base.php#L980

Bug is in:

isset($prop)?
    $prop:
    $frac?strlen($frac)-2:0,

which should be:

isset($prop)?
    $prop:
    ($frac?strlen($frac)-2:0),

Note parentheses around second ternary. You've been hit by PHP's ternary design bug.

PS. Could You make some tests to check for formatting bugs?
