CPT selector to “Recent Posts” widget

[sippis]

I think that "Recent Posts" widget should support selection to show all posts or only in selected CPT.

My first patch, be nice :p

Selector is displayed only if there is post types that are not built in and those are public, it defaults to 'post' and also allows to choose that or 'any' alongside CPT's.

Patch contains two new filters;

• widget_posts_cpt_args to change arguments passed for get_post_types
• widget_posts_cpt_selector if false, selector will not be displayed

Yes, most of users probably will not need this functionality and will get confused when they see it. However, as a developer, it's annoying to invent the wheel again every single time and make own widget for this functionality when there is already good basic widget for recent posts.

I would suggest to use 'post_type' instead of 'cpt' for the argument.

Next to that, what if I wanted to display two types of post-types instead of just one?
If you want to extend this functionality, I recommend to make it a bit broader (multi-select and array for options).

Patch would need a refresh to be considered. I'm just not sure if this is really needed by that many people.

Custom post types are usually very specific, like products or portfolio items. You don't really want to list those together with blog posts.
