[Improvement] Allow filtering in XHProf profile results

[indykoning]

The XHProf tab is incredibly useful for diagnosing performance problems.
But in a large project the Top functions unfortunately becomes too bloated with vendor packages.
So improvements in one's own code is more difficult to find.

My suggestion is to add an input you can use (a regex?) in order to filter these results

Hi @indykoning It is a great idea. We will investigate it after v2 release
