[.Shuggles.] Config Handler Script バージョン 0.61

The purpose of the Config Handler script is to read configuration notecards. It provides
a link message interface to get and set configuration options in different sections which
is described in detail in the included documentation. It also allows several options to
be on one line (separated by "|") to increase reading speed:

----------------------------------------------------------------
# Example
General option 1=Value
General option 2=Another value
[Section 1]
Option 1=Value 1
Option 2=Value 2
Option 3=Value 3|Option 4=Value 4|Option 5=Value 5
[Section 2]
List item 1
List item 2
List item 3|List item 4|List item 5
----------------------------------------------------------------

Interface:

- read (from notecard) and write (to local chat) config
- optionally append to existing config or explicitly clear it
- get sections and number of sections
- get and set values by name or index
- add values at the end of a section
- delete values by name, index or value
- remove whole sections
- get names and values in a section as well as their number
- error codes and human-readable error messages

PLEASE NOTE: This version is incompatible with previous releases because it uses "|" as
separator in messages now instead of ":" and section names are case-insensitive now. That
means that all scripts using the Config Handler need to be adjusted. It also affects the
Slideshow and Tip Jar scripts which will be updated in Slideshow v0.58 and Tip Jar v0.63.

The Config Handler script is full perm, so it can be adapted to your needs and
requirements. It's licensed under the BSD license with the addition that it must not be
resold or otherwise given away standalone in parts or as whole. It can be used in your
creations as long as these license conditions are met. Please remember to remove either
copy or transfer permissions on the script before you put your products on sale.

The Config Handler package contains a full perm test script to test some typical usecases
and special cases as well as a simpler example script. Both can be taken as reference on
how to operate the actual Config Handler script. Just rez a prim, drop the Config Handler
and Config Test scripts as well as the Example Config in and touch it. Check the output
manually. Be sure to verify your usecases as well.
