Jack Christensen e29574d447 Add support for integer, float and text arrays 
Restructure internals a bit so pgx/stdlib can turn off binary encoding and
receive text back for array types.

Jack Christensen 61bf7d841a Always use bound parameters 
PostgreSQL has two string syntaxes, one that allows backslash escapes and one
that does not (SQL standard conforming strings). By default PostgreSQL uses
standard conforming strings. QuoteString was only designed for use with
standard conforming strings. If PostgreSQL was configured with certain
combinations of the standard_conforming_strings and backslash_quote settings,
QuoteString may not correctly sanitize strings. QuoteString was only used in
unprepared queries, bound parameters are used for prepared queries.

This commit alters pgx to use always use bound parameters.

As a consequence of never doing string interpolation there is no need to have
separate Text and Binary encoders. There is now only the Encoder interface.

This change had a negative effect on the performance of simple unprepared
queries, but prepared statements should already be used for performance.

fixes #26

Jack Christensen ed2b3b3b49 Add timestamp support 
But not to NullTime because of text vs binary encoding difficulties.

You really should never use timestamp anyway.
