First Tagged Release (19-Aug-2017)

I'm adding a tagged release to FlameGraph so that package maintainers can grab a static version. There's nothing really special about this v1.0 release, other than it reflecting a stable body of code that is in widespread use, and recently merged a number of fixes.

Recent changes/fixes include:

• fixing a small floating point issue with search's total percent which is now more accurate #140
• stackcollapse-perf.pl now supports multiple event sources #136
• fixing a title overlap issue with large --height #125
• adding an optional subtitle (--subtitle) fad6bf7
• embedded notes (--notes) cef340b
• improving code annotations for Linux perf (used by some palettes) 99972c0 e83d1bc
• add --addrs option to include addresses on unknown frames #124
• treat input as UTF-8, to avoid some unicode characters breaking zoom #133

And some minor improvements to the test files.
