Added error handler for ipa_cmd().

The ipa_cmd() has been modified such that when an error occurs a
dialog box will appear showing the error message with 2 buttons:
Retry and Cancel. If Retry is clicked, it will attempt to execute
the same operation again. If Cancel is clicked, the operation will
be canceled and the control is returned to the caller.

New unit tests have been added to test ipa_cmd() on successfull
and unsuccessfull cases.

The associate.js, details.js, entity.js, search.js, and webui.js
have been modified to display the error message inside the page.
This behavior can be changed in the future (e.g. redirect to error
page).

The navigation.js and webui.js have been modified to render only
the visible tabs. This improves the performance and reduce hidden
errors. The navigation unit test has been modified to reflect this
behavior.

Some variables/functions also have been renamed for consistency.
