Log Message:
Update to version 0.8.10, based on PR #32432 from Juha-Matti Tilli:
- Recode support
- Isupport (005 numeric)
- Passive DCC support.
- Many memleak fixes.
- Network specific ignoring.
- Updated internal error handling.
- Complete 64bit support.
- Revised default aliases.
- Updated paste detection and settings.
- Tons of bugfixes.
- Other changes

The 'pre-install' hack from the pr is no longer needed after a fix from
jlam. Don't delete the patch-ae, which was removed in the pr.
Recode support won't work at the moment on NetBSD.

Bump the version for irssi-icb, due too the upgrade of irssi.
