Installing, activating, deactivating, and deleting a plugin does not wipe/clear the cache

[raamdev]

As of Quick Cache v150129, installing, activating, deactivating, and deleting a plugin does not wipe/clear the cache. This is unexpected behavior; I would expect it to clear the cache upon any of those events, since plugins often make front-end changes.

As of v150129, we have auto-clear handlers for active plugin upgrades, but not for installing, activating, deactivating, deleting plugins.

Related to #308.

Need to test if this issue is still applicable with the latest version of ZenCache Lite and ZenCache Pro.

Next Pro Release Changelog:

• Enhancement: ZenCache now clears the cache whenever a WordPress plugin is activated or deactivated. Many WordPress plugins change content on the front-end of the site, so this enhancement ensures that an old cache file is never served to visitors. If you want to disable this automatic behavior, see this article. Props @renzms. See Issue #424.
