Upgrade to latest PCRE #30

e is using a very old PCRE library (7.6). While trying to build e linking dynamically to PCRE 7.9 I found that ucp.h no longer exists, digging through PCRE changelogs I found: (Version 7.8 05-Sep-08)

"Replaced UCP searching code with optimized version as implemented for Ad Muncher ( by Peter Kankowski. This uses a two-stage table and inline lookup instead of a function, giving speed ups of 2 to 5 times on some simple patterns that I tested. Permission was given to distribute the script that generates the tables (it's not in the tarball, but is in the Subversion repository)"

2 to 5 speed up sounds nice, I have no idea how difficult the ABI changes are to implement.
