spark 1.5.2

Hello everyone, update time!

If you like spark, please consider leaving a review or giving it a star on GitHub!

On with the changes...

Added support for async-profiler

• async-profiler has been integrated into spark as a new profiler engine.
• It is currently supported for Linux x86_64 servers only, the existing Java (WarmRoast) profiler will continue to be maintained for other systems and modes (like --only-ticks-over).
• It's much more accurate and has a lower profiling overhead than the existing engine - win win!

Added permissions for sub-commands instead of just requiring 'spark'

• Sorry it took so long.. I of all people should know better!

Website/viewer changes and improvements

• Deployed a new documentation site
• Lots of style changes/improvements, added a new(ish) logo
• Deobfuscation mappings are now applied automatically
• Re-added the search bar - finally!
• Re-added highlight/bookmarks, these are now encoded in the URL so you can share specific points in a profile with others easily

Fixed some bugs

• The main one was "fix a bug upon early server startup in which percentiles would throw an out of bounds exception" - thanks to astei for that fix!

That's all I got for ya, until next time...
