Stub out log writing for this as it breaks Travis CI.
Remove DSLParser.
Fix bug which prevented client apps starting.
Add Buffers module;

- The Buffers module now holds the 'next', 'current' and 'old' buffers.
- Remove all 'buffer' related code from Interface, this means that events don't accumulate from the creation of new instances of Interface, it also reduces mutation on Interface.
Fix rendering;

- Render was spending time parsing lines and streams when there was no need, the line length is now checked ahead of time, and if it fits, we move on.
- The cursor was not being returned to the beginning of the line after writing the line, by fixing this, data no longer 'bleeds out' of the interface.
Redundant.
