config: replace triggers with hooks

Deprecate triggers and replace them with hooks. Now that aerc supports
running arbitrary ex commands over IPC, it is possible to run internal
aerc commands *and* shell commands via external shell scripts. Hooks
only allow running shell commands. Hooks info is passed via environment
variables.
