api explorer should follow coding standards

This one came up at the Toronto developer training.

The civicrm/api/explorer does a wonderful of job providing PHP that can be cut and pasted into a script, but unfortunately it doesn't follow the whitespace coding standards at http://drupal.org/coding-standards#indenting

Function Calls

Functions should be called with no spaces between the function name, the opening parenthesis, and the first parameter; spaces between commas and each parameter, and no space between the last parameter, the closing parenthesis, and the semicolon. Here's an example:

$var = foo($bar, $baz, $quux);

As displayed above, there should be one space on either side of an equals sign used to assign the return value of a function to a variable.
