invalid calls to mod_zoom_external

[danmarsden]

c522487 renamed mod_zoom_external to mod_zoom\external

but... events.php still refers to mod_zoom_external, and so does classes/output/mobile.php

[danmarsden]

this triggers the following unit test failures:

There were 2 errors:

1. core\externallib_test::test_all_external_info with data set "mod_zoom_get_state" (stdClass Object (...))
   coding_exception: Coding error detected, it must be fixed by a programmer: Cannot find external class mod_zoom_external
