mod_invites_page: Remove preauth URI button
This button is incompatible with the majority of XMPP clients around, yet based
on feedback from users, many are drawn to click it when they have any XMPP client
installed already.
In the case where the user already has software installed, we would prefer them to
select it from the software list so they can follow the setup process suited to
their specific client (we already track which software supports preauth URIs). If
their client is not listed, they can still use the manual registration link instead.

| 8 Introduction | |
| 9 ============ | |
| 10 | |
| 11 This module attemtps to provide a storage driver that is really multiple | |
| 12 storage drivers. This could be used for storage error tolerance or | |
| 13 caching of data in a faster storage driver. | |
| 14 | |
| 15 Configuration | |
| 16 ============= | |
| 17 | |
| 18 An example: | |
| 19 | |
| 20 ``` {.lua} | |
| 21 storage = "multi" | |
| 22 storage_multi_policy = "all" | |
| 23 storage_multi = { | |
| 24 "memory", | |
| 25 "internal", | |
| 26 "sql" | |
| 27 } | |
| 28 ``` | |
| 29 | |
| 30 Here data would be first read from or written to [mod\_storage\_memory], | |
| 31 then internal storage, then SQL storage. For reads, the first successful | |
| 32 read will be used. For writes, it depends on the `storage_multi_policy` | |
| 33 option. If set to `"all"`, then all storage backends must report success | |
| 34 for the write to be considered successful. Other options are `"one"` and | |
| 35 `"majority"`. |
