[RFC] PEAR::Pager changes

Hi, I've done a lot of work on the PEAR::Pager class, and I'd like to collect some opinions before committing them. Basically, I've added all the options that were already available in Pager_Sliding, for a complete customization. My primary concern was BC, so I've kept everything as it was before, even the default values for each option are set to match the previous Pager version. If you upgrade this class, without setting any new option, you should notice no changes at all. With these changes, Pager and Pager_Sliding are 100% interchangeable, you can switch back and forth one another just changing the included file and the class name. Now you can use Pager with mod_rewrite, customize every single appearance aspect you'd like to, there's even an improved error handling that lets you specify the PEAR_ERROR mode. Technically, I could even write a common base class as a wrapper for the two, and merge the two packages in one, but I still haven't a strong opinion about that. I'm here to listen to yours, anyway :-) The *ONLY* BC change I had to introduce was in getLinks() method. WAS: getLinks($back_html='<< PREV', $next_html='NEXT >>'; NOW IS: getLinks($pageID=null, $back_html='', $next_html=''); i.e. the two parameters are shifted one position forward to leave room for the new parameter. The two old parameter are deprecated, BTW, since now you can set them in the constructor, as common options. (I removed the default values since they're already set class-wide). This change will affect only those who used this method with values different from the default ones. While externally everything is left as it was before, the internals are quite different, so I won't provide a diff since there are just too many changes.
