cgi-sample search form; texinfo fix; xml scaffold; help, man pages etc. visited; screen output, color set to true; docbook entries removed

* cgi generated sample search form
  * order results on files of the same title, in multiple files (with
    different filenames)
  * postgresql, character case sensitivity, control, on/off
  * tail decoration, gplv3 & sisu info

* texinfo/info (pinfo) module starts to do something vaguely useful again
  [not a much used module, testing required]

* print XML rendition of document structure to screen -T

* sisurc.yml default, color set to true
  [apologies if this causes anyone any inconvenience, it is configurable in
  sisurc.yml]

* help, man pages, README (man(8) related and env, 'sisu -V')

* docbook entries removed for the present time

* sisu-install (install ruby rant script renamed) and permissions set to
  executable
