Shortcode parsing does not allow standalone variables (Shortcake issue)

[oherman]

Shortcake can allow and parse variables with values
eg. [mycode src=someplaceinthenet]

but WILL NOT PARSE NOR ALLOW THIS KIND OF CODE
eg. [mycode someplaceintenet]

Called as standalone variables for easier identification, these kinds cannot be easily generated within shortcake.

These standalone variables are parsed as
$attr[0], $attr[1] and so on...

while normal variables are passed as
$attr('src' => 'value')

Shortcake generates values to pass on to shortcodes by this method:

array(
'label' => 'IFrame embed code',
'attr' => 'content',
'type' => 'textarea',
'description' => 'Enter embed code generated from Google Maps.',
),

It has no provisions for sending standalone variables.

A fix for this issue requires a change in shortcake.

This is an unresolved Shortcake issue wp-shortcake/shortcake#128

Might consider contributing to them to fix it

Submitted a fix to Shortcake wp-shortcake/shortcake#180

If the pull request goes through, we should remove our own implementation sandwich-googlemaps then do a remove_shortcode then add_shortcode on googlemaps to re-implement it. We can end up with 1 shortcode that works with Jetpack's googlemaps shortcode
