Remove extra spaces on welcome text

Must be feeling OCD today. The console output had 2 spaces between "2.3-ALPHA" and "on the". I also removed the space before "..." because all the subsequent lines of console output have no space before the "...'.
Actually this is a title line, so maybe the "..." could be deleted here also :)

Nuke fifolog support. It was never used or fully implemented, no GUI option, and didn't end up working out.
It buffered writes too long, users could never see the most current log data.

Rework pfSense-upgrade script to make it work with nanobsd

Introduce read_global_var:

- Add a new script, read_global_var, that returns the value of any item
contained in global array $g
- Replace all grep and sed magic from shell scripts

Introduce read_xml_tag.sh

Create /usr/local/sbin/read_xml_tag.sh, that will read a xml tag from
config file using xmllint. Replace all direct read using cat, grep, sed,
... by this script

One more hardcoded pfSense name

Consider globals_override.inc and replace hard coded pfSense string by product_name

Create symlinks during the boot for nanobsd

Make sure pkg db and cache is safe on nanobsd and on pfSense with /var mounted as MFS
