code cleanup!

Improve field sync performance

Improve `/database/:id/fields` response time

Previously the code would individually insert any new column found as
a row in the fields table. This commit switches that processing to be
chunked. This significantly increases performance of sync when there
are many new columns being sync'd (i.e. when adding a new database).

Fix empty dashboard archival notification

Don't show "Add this to dashboard" if modifying existing question

Previously every metabase field was updated during sync, giving it a
new updated_at value even if there was no change. This commit will
only update a row if there's been a base_type change or a new special
type was found (which should be pretty rare). This significantly
increases the performance of sync, especially on installs with larger
numbers of columns being sync'd.

Previously we would use the default behavior, which is
`ring.middleware.json/wrap-json-response`. `wrap-json-response` will
generate a string from the Clojure data structure and use that as the
ring response. This commit switches serializing to a
`PipedInputStream` which allows us to use less memory and return the
results as we are serializing them to JSON.

Change inline code markdown to display as inline in text dashcards. Up dashcard breakpoint showing markdown help link

 Remove HTTP connection closing tests 

This is a test only change to introduce coordination between the
threads and remove the timing sensitive sleeps previously used in the
streaming tests.

i18n for Admin Panel Settings section (WIP)

These tests essentially cover Jetty's ability to notice a connection
has been closed and reap that connection by interrupting the thread
that our handler is running on. We don't set anything changing this
default behavior, we don't handle the InterruptedException. That
exception just gets bubbled up, and handled by Jetty.
