When this form is submitted, emhttp will see a GET request like this:
"GET /update.htm?cmd=/etc/rc.d/rc.slimserver&arg1=enable&arg2=/usr/local/slimserver&runCmd=Apply"
(Actually arg1 can be 'enable' or 'disable' and arg2 is the directory in the form box, provided the
field is not disabled.)
The 'runCmd=Apply' tells emhttp to run the command given by 'cmd' with arguments 'arg1', 'arg2', ...
In this case it will run: "/etc/rc.d/rc.slimserver enable /usr/local/slimserver"
The output of this command will show up in the 'progress frame' of the webpage.
We have thus constructed the form to control slimserver via the rc.slimserver script.
The bit of javascript just causes the INSTALLDIR box to be edit-able only if slimserver is disabled
and the user is about to transition it back to enabled. Simple eh?

/**
* Converts to and from JSON format.
*
* JSON (JavaScript Object Notation) is a lightweight data-interchange
* format. It is easy for humans to read and write. It is easy for machines
* to parse and generate. It is based on a subset of the JavaScript
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
* This feature can also be found in Python. JSON is a text format that is
* completely language independent but uses conventions that are familiar
* to programmers of the C-family of languages, including C, C++, C#, Java,
* JavaScript, Perl, TCL, and many others. These properties make JSON an
* ideal data-interchange language.
*
* This package provides a simple encoder and decoder for JSON notation. It
* is intended for use with client-side Javascript applications that make
* use of HTTPRequest to perform server communication functions - data can
* be encoded into JSON notation for use in a client-side javascript, or
* decoded from incoming Javascript requests. JSON format is native to
* Javascript, and can be directly eval()'ed with no further parsing
* overhead
*
* All strings should be in ASCII or UTF-8 format!
