Added FlameChart view for profiler

[paales]

Allows us to create profiler charts like this: http://cloud.h-o.nl/rI1W

It could still use some work, but it was way more helpfull than the current table, which was way to big to say anything usefull.

Possible improvements:

• Memory Flame Chart, where not the time, but the memory usage is displayed as width.
• Bottom up flame chart: Multiple sections can call the same eventual method, grouping those together would be nice (not sure how that would look)
• Mouse controll: zoom + scroll like in Chrome Inspector.
• Integrate queries
• Colorcode types of profiles: templates, queries, \Template classes, dataprofiler, etc. Support for the profiler tags.
