minor change to microtime parser
Another fix to the no-longer-flimsy trace array detection
Two new features: combine modifiers and automatic return-instead-of-output.

Kint will now detect when its output is assigned to something, making the @ modifier redundant in the process.

$k = Kint::dump($var);

will automatically return the output and assign it to $k, additionally, you can save output with modifiers by prefixing the variable instead of the call to kint:

!+$k = d($var);

Adding modifiers to kint instead of the variable would not produce output: $a = @!d($var); would always return false for example.

todo: each assignment gets whole JS&CSS in rich output mode.
