Use freeciv trunk r22791
Have network capstrings in version.txt and replace upstream one with
freeciv-web one by sed script instead of applying patch with the change.
This is much easier to maintain than to create new patch every time
either of the capstrings change.
Updated patches README.
Renamed freeciv.net-bootstrap.sh as freeciv-web-bootstrap.sh and made
a number of easy fixes to it, and added comments about remaining problems.
Replaced README references to "freeciv.net" with "freeciv-web"
Set executable bit for fc_version after regenerating it.
