fixed bug in entering directly into message

when the message isn't on the first page

moved a bunch of view stuff into internal/views

rewrote a bunch of code that I hated

allow comma separated kafka broker args

Truncate large messages in partition view.

If the kafka messages are large kcli can hog
a lot of memory.  This commit truncates the
in memory messages to the width of the screen.

moved search dialog down

Delete get-kafkas.sh

don't clear flash message if searching or jumping

added filtering

show raw message if not json
