Added support for defining more that one entity per file using Logtalk

on single entity source files plus loading and compiling helper files.
Updated the URL used on the automatically generated XML documenting files
when compiling entities with the option doctype(web).
Improved error checking when compiling calls to the {}/1 control construct.
Corrected several typos and some outdated links on the Logtalk manuals.

<h2>Defining a list protocol<a name="protocol"></a></h2>
<p>
As we saw in the above example, a Logtalk object may contain predicate directives and predicate definitions. The set of predicate directives defines what we call the object's <em>protocol</em> or interface. An interface may have several implementations. For instance, we may want to define a new object that implements the list predicates using difference lists. However, we do not want to repeat the predicate directives in the new object. Therefore, what we need is to split the object's protocol from the object's predicate definitions by defining a new Logtalk entity called a protocol. Logtalk protocols are compilations units, at the same level as objects and categories. That said, let us define a <code>listp</code> protocol:
