[Profiler] make it possible to omit the link var

xabbuh · xabbuh · commit 7ff7ce72ef61 · 2016-01-16T16:28:25.000+01:00
Currently, when you do not want to have a section in the web profiler,
you would have to explicitly pass `false` as value for the `link`
variable. With this change you can omit it when including the toolbar
item template.
