[Freeciv-Dev] Patch: Gui independent help for tech

[Marko Lindqvist <caz@xxxxxxxxxxxxxxxx>]

 This patch creates some gui dependent show_xxx_help_label() -functions
that can be called from common help parsing code. Also creates
create_tech_help() that uses those functions to create parts of tech help.

 - create_tech_help() is used by GTK and XAW clients. MUI does not use
   this system, but should compile ok (can't test).
 - Governments allowed by tech are no longer listed at help text, but
   are also parsed by this system. For XAW this changes nothing, but
   GTK creates link to government help page. 


 TODO:

 - Similar help parsing for units, buildings and governments.
 - More help label styles (more show_xxx_help_label() -functions)
 - Text alignment in requested column.
