Quote identifiers more intelligently.

If a table/column name was given as schema.table or table.column, passing it
straight to DBI's `quote_identifier` will quote the whole thing, which will
break the meaning.

Replace calls to DBI's `quote_identifier` with a new wrapper,
`_quote_identifier`, which splits on `.` first, quotes each part, and returns
the concatenated result, so e.g. `foo.bar` becomes `"foo"."bar"`.

Fixes Issue #31

Thanks to nicolasfranck for reporting this problem on GitHub, and sorry it took
so long to get it sorted.
Update changes to reflect limit arg validation change
Be more consistent.
Allow a false value for connection_check_threshold to disable checking.

At the moment, if connection_check_threshold is not supplied, or has a false
value, we default to 30 seconds.  We should default it it isn't supplied, but
if it's supplied with a false value, we should take that to mean that we should
not perform connectivity checks.

This addresses the point raised in GH #22 - that connectivity checking cannot be
disabled - which may be desireable if using the DBI `mysql_auto_reconnect`
attribute instead.

Bump version - 2.00!

(I'm in two minds about whether this release warrants the version jump; I'm
going with it simply because this version introduces support for Dancer 2.)

Log more helpful error if asked for non-existent default conn

If the user calls database() with no connection name, but doesn't have a default
connection configured, it makes sense to throw a more illuminating message.
