Array keys are encoded incorrectly

[intypica]

http_build_query encodes JSON arrays incorrectly, resulting in unexpected behavior when using arrays as view keys.

Example:

$params = array(
"startkey" => array( 'foo' ),
"endkey" => array( 'foo', array() )
);

Is expected to produce:

?startkey=['foo']&endkey=['foo',[]]

But produced completey encoded strings instead:

startkey=%5B%22foo%22%5D&endkey=%5B%22foo%22%2C%5B%5D%5D

There was also an issue with passing boolean keys as couchdb expects them. For example:

descending=true
