Enhanced user and orgs tables in admin view.

- Changed the table layout a bit.
- Added functions to the tables:
  + Search
  + Sort
  + Paginate

Updated the config options descriptions.

Made some small changes to the description of the config options for
SMTP. Some were a bit cryptic and missing some extra descriptions.

Also made it more clear which type of secured smtp connection is going
to used.

Format some common Lettre errors a bit simpler

Currently when for example using the admin interface to send out a test e-mail just
returns `SmtpError`. This is not very helpful. What i have done.

- Match some common Lettre errors to return the error message.
- Other errors will just be passed on as before.

Some small other changes:
- Fixed a clippy warning about using clone().
- Fixed a typo where Lettere was spelled with one t.

Fixed creating a new organization

- The new web-vault needs a new api endpoint.
- Added this new endpoint.

Fixes #1139

Simplify implementation of `UserOrgType::cmp()`

Allow multiple SMTP Auth meganisms.

Updated lettre (and other crates) and workflow.

Also move `UserOrgType::from_str()` closer to the definition of `UserOrgType`
since it references specific enum values.

- Allow all SMTP Auth meganisms supported by Lettre.
- The config value order is leading and values can be separated by a
  comma ','
- Case doesn't matter, and invalid values are ignored.
- Warning is printed when no valid value is found at all.

General:
- Updated several dependancies

Lettre:
- Updateded lettere and the workflow
- Changed encoding to base64
- Convert unix newlines to dos newlines for e-mails.
- Created custom e-mail boundary (auto generated could cause errors)

Tested the e-mails sent using several clients (Linux, Windows, MacOS, Web).
Run msglint (https://tools.ietf.org/tools/msglint/) on the generated e-mails until all errors were gone.

Lettre has changed quite some stuff compared between alpha.1 and alpha.2, i haven't noticed any issues sending e-mails during my tests.

Hide ciphers from non-selected collections for org owners/admins

Fixing MsgPack headers type and support mobile SignalR

If org owners/admins set their org access to only include selected
collections, then ciphers from non-selected collections shouldn't
appear in "My Vault". This matches the upstream behavior.

Clarify multiuser capabilities

Fix the Alpine build

Delete associated favorites when deleting a cipher or user

This prevents foreign key constraint violations.

Diesel requires the following changes:
- Separate connection and pool types per connection, the generate_connections! macro generates an enum with a variant per db type
- Separate migrations and schemas, these were always imported as one type depending on db feature, now they are all imported under different module names
- Separate model objects per connection, the db_object! macro generates one object for each connection with the diesel macros, a generic object, and methods to convert between the connection-specific and the generic ones
- Separate connection queries, the db_run! macro allows writing only one that gets compiled for all databases or multiple ones
