/**
* GetHTML
* Gets the html for the particular form type and form design that is loaded.
* This will also load up custom fields, put them into the form, add format choice dropdown (if applicable) and finally return the form html for displaying or putting on a website.
* If it's a modify details form, then there are placeholders put into the form so the calling object/method can pre-fill the form as necessary.
*
* @param Boolean $inside_sendstudio Pass in whether we are viewing the form from inside the application or not. This allows us to include/exclude information accordingly. This stops a problem where viewing a form will log you out of the admin control panel.
*
* @see GetFormDesign
* @see FetchFile
* @see formtype
* @see chooseformat
* @see changeformat
* @see lists
* @see customfields
*
* @return String Returns the form's html content.
