unrealircd: Update to 5.0.8

UnrealIRCd 5.0.8 Release Notes
===============================

The main purpose of this release is to enhance the
[reputation](https://www.unrealircd.org/docs/Reputation_score)
functionality. There have also been some other changes and minor
bug fixes. For more information, see below.

Enhancements:
* Support for [security \ 
groups](https://www.unrealircd.org/docs/Security-group_block),
  of which four groups always exist by default: known-users, unknown-users,
  tls-users and tls-and-known-users.
* New extended ban ```~G:securitygroupname```. Typical usage would be
  ```MODE #chan +b ~G:unknown-users``` which will ban all users from the
  channel that are not identified to services and have a reputation
  score below 25 (by default). The exact settings can be tweaked in the
  [security group block](https://www.unrealircd.org/docs/Security-group_block).
* The reputation command (IRCOp-only) has been extended to make it
  easier to look for potential troublemakers:
  * ```REPUTATION Nick``` shows reputation about the nick name
  * ```REPUTATION IP``` shows reputation about the IP address
  * ```REPUTATION #channel``` lists users in channel with their reputation score
  * ```REPUTATION <NN``` lists users with reputation scores below value NN
* Only send the first 1000 matches on ```STATS gline``` or a
  similar command. This to prevent the IRCOp from being flooded off.
  This value can be changed via
  \ 
[set::max-stats-matches](https://www.unrealircd.org/docs/Set_block#set::max-stats-matches)
* Warn when the SSL/TLS server certificate is expired or expires soon
  (within 7 days).
* New option allow::options::reject-on-auth-failure if you want to
  stop matching on a passworded allow block, see the
  [allow password \ 
documentation](https://www.unrealircd.org/docs/Allow_block#password)
  for more information. Note that most people won't use this.

Fixes:
* The ```WHO``` command searched on nick name even if it was told
  to search on a specific account name via WHOX options.
* Some typos in the Config script and a warning
* Counting clients twice in some circumstances

Changes:
* Support for $(DESTDIR) in 'make install' if packaging for a distro
* Mention the ban reason in Q-line server notices
* Add self-test to module manager and improve the error message in case
  the IRCd source directory does not exist.
* Print out a more helpful error if you run the unrealircd binary
  rather than the unrealircd script with an argument like 'mkpasswd' etc.
* On *NIX create a symlink 'source' to the UnrealIRCd source

Module coders / Developers:
* The [Doxygen module API docs](https://www.unrealircd.org/api/5/index.html)
  have been improved, in particular the
  [Hook API](https://www.unrealircd.org/api/5/group__HookAPI.html)
  is now 100% documented.
