Plugins page pagination links disabled for Must-use plugins / Incorrect path displayed in must-use help text

[dd32]

2 issues:

• When you have more Mustuse/dropins enabled than "Plugins per page" the Pagination links are not shown, allowing you to only see page1.
  • Original idea seems to be that pagination would be disabled on these pages, I feel that we should respect the pagination settings here..
• The help text on the must use page references wp-content/mu-plugins directly without taking into account WPMU_PLUGIN_DIR's value

These both would apply to 3.1 as well, except the string change wouldn't be worth it for 3.1

Chances are small that someone would set their plugins per page to less than the number of MU plugins they've got loaded however.

In [17806]:

• Allow Pagination for Must-Use/Dropin plugins
• Respect WP_CONTENT_DIR & WPMU_PLUGIN_DIR for help text
• Move help text into WP_Plugins_List_Table

See #17327

Fixes #17327 for 3.1

This came up on a live MU install, It was set to 10 plugins per page, and 15 MU plugins were in use.
leading to confusion as apparantly a plugin wasn't activated, yet was still running (as it wasn't showing up in any admin page as being there)
