[Plugin: Google Analytics for WordPress] Coding issues and E_STRICT spam

Using PHP 5.3 or 5.4 will generate (tons of) log entries for invalid static access of non-static properties for GA_Filter.

Quick fix: all methods of GA_Filter are *only* used in static context and should be declared with static public.

Some minor issues:
for googleanalytics.php
line 24: plugin_dir_path( __FILE__ ) does add a trailing slash. Not needed to do so twice.

line 1510: $gaf = new GA_Filter(); is not used by the plugin.
There is no need for it, as the interface is static already.

wp-gdata.php:
For consistence either omit all public in public function or always use it.

If time permits I’ll add a more complete coding review later this year (basic consistency, common error and performance checkup. maybe something about missing source documentation too).
