[Seaside] Improved HTML error handler

[Sabine Manaa]

Hi Cyril,

I have an error Handler which resumes (if possible), shows a message to the
user and sends an email to me with the stack and further information.  If
you have questions, ask.

1) when registering the application: I attach  it to the RequestHandler:
"exceptionHandler: RKAHtmlErrorHandler"
2) the file out code of the error handler is below
3) an example of the mail in separate mail
4) also, when an error occurs (i catch them with an exception handler
overall), I create an instance of it
RKAHtmlErrorHandler
session: self requestContext session
stack: thisContext stack
exception: anException
ip: self ipAddressString
view: self class printString.

As you see in the timestamps, I use it for years now. Possibly some methods
are no longer used (especially the hard coded mail html code), I should do
a refactoring there:-). But always other topics. I hope it helps anyway
.

5) In my main layout view, I do this in the renderContentOn:
html document addLoadScript:
(html jQuery document onAjaxError: (self ajaxErrorHandler asFunction:
#('event' 'jqxhr' 'settings' 'exception')))

ajaxErrorHandler
^ ' if (jqxhr.status == 403) {
            alert("Aus Sicherheitsgründen wurde Ihre Sitzung beendet. Bitte
melden Sie sich neu an.");
            window.location.href =
settings.url.split("?")[0].replace("help","");
        } else {
if (jqxhr.status == 200) { } else {
alert("Entschuldigung, es ist ein Fehler aufgetreten. Bitte melden Sie sich
neu an und versuchen es erneut oder geben Sie uns eine Info über den
folgenden Fehler: " + exception +"jqxhr.status:"+jqxhr.status);
        }}'

Concerning the missing features for the v2, I was missing the following:

1) https://github.com/google/material-design-lite/issues/943
I fixed it by changing the overflow: to visible in mdl-card
2) date picker
I just started using
https://puranjayjain.github.io/md-date-time-picker/#documentation/time
3) same for time picker
so it seems that we will go online with v1. Too many changes in v2which
would take more time for us to go online

I hope the code helps
Regards
Sabine
