Fixes bugs: dialog's help icon location and port order

This commit fixes two bugs. The first one is related to the location of
the help icon used in the generated operation dialogs that it is used to
replace the description text, so that the text appears as a tooltip of
these icons. The code that replaces the description with this icons had
some bugs that caused the application to fail with certain
configurations.

The second bug was related to the port sorting comparator used in the
OperationDefinition class. The comparator didn't follow the comparator's
contract, causing the code to fail, for example, when to ports don't
have a specific port order.

Updates starting instructions in docs to new project layout

Adds the new /dist directory in starting instructions.

Fix AIBenchJTreeManager

An error was detected in the AIBenchJTreeManager, caused by the
datatypes that do not have an associated icon. The current code tried to
recover their icon as a global resource and, as the icon URL was null,
it caused an error.

This commit fixes this error by checking first whether the icon URL is
null or not.

In addition, this commit also simplifies some additional code in the
same class.
