#31 Remove output buffering in favour of separate log files

[Derek Battams]

Current MRE buffers all output and dumps it to a
specified log file. This is not flexible as it doesn't
allow for easy filtering of output. Instead, remove
all output buffering and replace it with separate log
files for separate events. Currently, I'm supporting
three types of logs: log (general messages), debug
(debug messages) and exception (thrown exception
output). This may change as I do it, but the bottom
line is that the inflexible output buffering code has
got to go.
