Created wc_add_help_tip() function to generate the icons
Replaced all .help_tip elements and [?]
We'll keep the old image and styles in order to maintain backwards
compatibility
Closes#9381
* fixed indentation - swapped spaces for tabs at start of line, swapped
tabs for spaces min-line for alignment
* removed instances of `@return void` and `@access public`
* improved readability

- Removed post type classes. Since they were always loaded, there was
no benefit having them split up. Combined meaning less hooked in
methods.
- Stopped loading some function files and sessions in the admin area.
They are not needed there.
- Made a few admin page classes static as they are stateless
