Weather alert content can overfill the message box

[neilswann80]

I noticed a recent weather alert contained so much content it overfilled the message box so you are unable to see/read the beginning of the message.

As there is no option to scroll within a message, perhaps break the content into multiple pages based on a max number of lines?

Alerts are currently shown through a call to the Dialog() function, https://github.com/orontee/taranis/blob/main/src/alerts.cc#L67. AFAICT this function doesn't support vertical scrolling.

The easiest solution is to elide the alert description after a fixed number of characters. Ugly. But other solutions look quite complicated to my eyes.

@neilswann80 Hey what was the location of that alert???

I just copy-pasted the lyrics of the song I was listening to in the first alert of my taranis.json file and with more or less 400 characters it looks ok!

Today's weather alert on Bristol, GB is an example of the overfill.

Oh, I see...

I'll investigate what scrollview.h in the SDK has to offer...

First step: Implement an alert viewer.
Next step: Plug ScrollView in the alert viewer...

Implemented using AddScrolledArea/RemoveScrolledArea and consuming EVT_SCROLL. Not very smooth and missing a scroll bar but good enough for such a marginal case where the alert description would fill the entire screen...
