Two methods for specifying tcl applications in ini file:
1) [DISPLAY]TKPKG specifies a tcl package by name
2) [DISPLAY]TKAPP specifies path to a tcl file to be sourced

Method 1) Supports fully integrated tcl packages and provisions for
          specifying packages with certain versions.

          When specifying a TKPKG, arguments applicable to the tcl
         "package require" command are allowed.

         Examples:
            TKPKG Thepkg                   (any version)
            TKPKG -exact Thepkg 1.0        (exactly version 1.0)
            TKPKG Thepkg 1.0               (version 1.0 or later)

Method 2) Supports direct sourcing of tcl scripts
         Examples:
            TKAPP /somefullpath/theapp.tcl (absolute addressing)
            TKAPP ./theapp.tcl             (relative addressing)

To allow these tcl applications to create new tab pages and find parameters in
the inifile, two new tcl procs are provided:

  dynamic_tab(name,text)   tcl interface to _dynamic_tab(name,text)
  inifindall(section,item) returns tcl list for all occurences for [SECTION]ITEM
