Show offending line if context provided to log_warn or log_err.

Perhaps use different colors for warn vs err? Probably should do colors only if a tty is detected.

I think is-terminal is the best current Rust solution for providing isatty functionality cross-platform?

Right now the logging system will show the line number, but we could easily go scan that line or just add the line content to the Context struct?

aving the line number should be easy to read the line from the file again, or just clone the line into the struct.

You can assign me to this one and the MAKE one

I guess this one can be closed since merging #9

Re-opening because I didn't realize the line isn't actually printed out anywhere just stored in the struct. I also adjusted it to store the line in the struct while parsing, which while uses a little bit more memory, is much faster than re-reading the line during logging.
