Add support for ctrl/modopts/*.ini

How these files differ from modopts.ini (and by extension,
ctrl/modopts.d/*.ini):

- The root section is always parsed, part of the returned object
- [sections] denote ARS that if matched (current user meets requirements)
  then those key/values are added as properties of the returned object
  possibly overriding previously defined properties (options), this allows
  different users (or clients/hosts, terminals) to get different option
  values much more easily

exec/load/modopts.js

-/* Load Synchronet JS Module Control/Enable options from ctrl/modopts.ini */
-/* Parse a single .ini section using the argument (to load) as the section name */
-/* and return an object containing the key=value pairs as properties */
-
-/* If the section [module:lang=user-lang] exists in the .ini file,
-   that section (or key value from it) will be returned instead of the [module] section.
-
-   If the section [module:charset=terminal-charset] exists in the .ini file,
-   that section (or key value from it) will be returned instead of the [module] section.

-/* To avoid over-writing the parent script's "argc" and "argv" values,
-   pass a scope object to load(), like this:
-
-   options=load(new Object, "modopts.js", "your_module_name");
+/* Load Synchronet JS Module simple control/enable/string options from
+ * ctrl/modopts.ini (and by extension ctrl/modopts.d/*.ini) or
+ * ctrl/modopts/modname.ini
+ *
+ * For ctrl/modopts.ini (and ctrl/modopts.d/*.ini): 
+ *   Parses a single .ini section using the first argument to load() as the
+ *   section name and return an object containing the section keys as
+ *   properties with Boolean, Number, or String values.
+ *
+ *   Or parses and return a single option/key value when a key name is
+ *   specified in the fourth argument to load(). The default value of the
+ *   option may be specified in the fifth argument to load() in this case.
+ *
+ *   If the section [module:lang=user-lang] exists in the modopts.ini file,
+ *   that section (or key value from it) may be returned instead of the
+ *   [module] section.
+ *
+ *   If the section [module:charset=terminal-charset] exists in the
+ *   modopts.ini file, that section (or key value from it) may be returned
+ *   instead of the [module] section.
+ *
+ * For ctrl/modopts/modname.ini:
+ *   Parses the entire root section of the modname.ini file and for each
+ *   [section] in the .ini file, treat the section name as an Access
+ *   Requirement String (ARS) and if the current user meets the requirements,
+ *   parse the keys from that section and add the keys/values as properties to
+ *   the returned object. Later sections/keys can override previous property
+ *   values.
+ *
+ *   If an option/key name is passed to load(), returns just that one option
+ *   value (String, Number, or Boolean, not an object).
+ *
+ * Examples:
+ *
+ * var options = load({}, "modopts.js", "your_module_name");
+ *
+ * var opt = load({}, "modopts.js", "your_module_name", "opt_name", default_opt_value);
