The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Previously we were using a library to colorize our strings during the
testdrive command. We used [white] which caused the output to not appear
on terminals that use white as the background. This change uses the
default terminal output color instead and only uses colorized strings
for warnings, errors and info via yellow, red and green respectively.
Hopefully those colours still show up on most terminals!
Bootstrap is meant for a system that sets itself up. This command is
more like a testing mode so I want to rename it to avoid confusion.
Fixes#129 and came out of #117.
