No longer hangs eggdrop event loop while getting data.

Added new feature to optionally output information to a file under the release path, for newdir/pre events.
Added option to use egghttp - needs testing on other versions of eggdrop.
The {*} will only work on TCL8.5; though 8.4 and older are already old, I'm undecisive if a versioncheck is appropriate. Adding a comment might be enough.
