Allow Numeric Slugs

Normally it is not possible to have a page slug (the page's name in the URL) that is a number. For example this will not work: yoursite.com/about/2/. That URL conflicts with paged content feature where you can posts and pages with multiple pages of content by adding <!--nextpage--> within your content. This plugin allows you to have pages with numbers as slugs by giving up the ability to have paged content pages which isn't a big deal as most people don't use paged content pages anyway. Code contributions and bug reports are welcome via this plugin's GitHub repository.

Version 3.0.0

• Ditch all of the old fragile hackery of this plugin in favor of just hooking into the WordPress function that ensures that slugs are unique. It's what was adding the -2 suffix in the first place.

Version 2.2.0

• Update for WordPress 4.4's rewrite rules.
• PHP 7 compatibility by renaming class constructor. Also drops unneeded references.

Version 2.1.0

• Update for WordPress 3.3's rewrite rules.

Version 2.0.1

• Re-add the save_post filter after fixing the slug incase multiple posts are updated in one pageload.

Version 2.0.0

• Recoded for WordPress 3.0+. WordPress now won't let you manually enter a numeric slug -- it will prefix "-2" onto the end of it so that the page is viewable. This new plugin version works around it.

Version 1.0.0

• Initial release.
