- build all tools using the Makefile and place them in ./build
- add copyright header to Makefile
- premix/readme.md edited to fix some errors, improve descriptions and
document Makefile usage
- link the Premix documentation in the main README.md
- also build `hunter` in the nimble tests
- refactored the file and directory search so all debugging tools can be run
from the top-level dir like this: `./build/<tool> ...`
- write all JSON debugging data in the current directory
- add JSON files generated in the top-level dir to .gitignore
- Nimbus now exits with an exception after dumping debug data and
running `premix` on it
- dependency repos moved to "vendor/<package name>"; delete
"vendor/repos" by hand after making sure it contains no unpushed work
- fixed the "validator_keygen" build and merged it with that of "beacon_node"
- replaced `nimble` with `nim` for compiling, since `nim` already knows
how to add the Nimble packages to its module path
- better target dependencies for "beacon_node" and "validator_keygen"
- isolate dependencies (both Git repos and ".nimble" dir) in "vendor"
- ensure that everything is compiled using our version of Nim with
something as simple as "make"
- pull the latest changes with "make update"
- re-create Nimble's package dir and re-build the Nim compiler automatically when needed
- "env.sh" script that can be used to prefix any command that needs to use
"nim" or "nimble" from our Nim repo
- move the top level nim.cfg to nimbus/nim.cfg so it doesn't apply to
deps
- "fetch-dlls" `make` target for Windows to get precompiled Snappy, RocksDB and SQLite DLLs
