v2.0.1 - Maintenance Release

Fixes:

• #57 Requests sent to routes with special characters like /path/** with throw exceptions. Fixed by @lustefaniak via #57 and previously by @wilaszekg via #55.
• #58 The instrumentation will now keep updating the operation name with further patch matchers unless the user explicitly sets an operation name via the operationName directive or directly calling Kamon.currentSpan().name(...). Fixed by @ivantopo via #61.
