f20fa5e995 Add User.get_fields(), and rework plugins to fix $nick broken expansions
User.nick is no longer a writable attribute since a085aed924, so it won't show up in __dict__ now.

get_fields() replaces the User.__dict__ hack various plugins used and also provides some new expansion variables:
- $sid and $server expand to the server ID and name respectively
- $modes and $channels are now preformatted strings
- $netname expands to the network name

$manipulatable and $_irc were removed since their values aren't quite meaningful as strings

6bb2198710 inspircd: move _modsupport.clear() to a _post_disconnect override
Speculative fix for #567.
This may be caused by a race condition between post_connect and handle_capab, since the remote server can send its server data before we start sending ours.

2245af1dba Revert "ts6: handle ChatIRCd ENCAP USERMODE"
This reverts commit 785fc8d2d2.

This feature isn't actually used yet and is relatively non-standard. Aside from that, the biggest issue so far is that ENCAP USERMODE doesn't give servers a way to explicitly acknowledge or reject(ignore) the mode change, which can lead to desyncs.
