Gotraceui v0.1.0

This is the first release of Gotraceui, the efficient frontend for Go execution traces. It is the culmination of nine months of work and over 700 commits.

The attached PDF is a manual explaining most aspects of Gotraceui, including how to install it.

All of the essential features are there and Gotraceui should be a better alternative to go tool trace in 90% of cases. Nevertheless, this is only the beginning.
