Add check for PHP XSLT Processor extension.

When the PHP XSLT Processor extension is not loaded, Islandora will
silently fail when attempting to add new objects.  This changeset
adds a check in the Islandora hook_requirements() hook for the
XSLTProcessor class.  If it isn't found, a message is thrown.

islandora_delete_object() now follows function description.

islandora_delete_object() no longer throws. Now it will only return TRUE if
successful, FALSE otherwise as expected.

This fixes the issue where solution packs were not reinstalling existing objects.
Added two helper functions.

islandora_user_access_all()
islandora_user_access_any()

They simplify checking for multiple permissions, either requiring all
or only one permission.
