[For 1.8] Bump Absorber 2.1.2

[Laird]

Bump Absorber inhibits thread bumps (by a new post) other than by the original poster (OP) after a stipulated bump interval (in hours) has elapsed since the last bump.

Installation is as usual: extract files, recursively copy files in root into your board's root directory, then install+activate via the ACP's Plugins page.

Note: requires patches to core files which are automatically applied on installation, and automatically reverted on uninstallation.

This plugin was written for a fee for @andrewjs18, who requested that it then be open sourced. OP Can Close Thread was then split out of it.

Version 2.0.0 has just been released:

• Given how distinct the thread-closing functionality is from the bump-absorbing functionality, the former has been split out into a separate plugin: OP Can Close Thread.
  
• Fixes a patch-reversion bug.

(Remember that upgrading requires uninstalling, reinstalling, then re-configuring settings).
