Consistent Status Display on All Supported Services

[caronc]

Description:

Related issue (if applicable): #691

Apprise carries a few entries as part of it's payload. The optional title, the body, and the type (whether it's an info, warning, error, etc).

The problem is the info doesn't get carried forward on a lot of different platforms, yet it does on others. due to the varying degree of support from one service to another, some support icons that change colors, but others are very text driven (like SMS messages).

For consistency, these text forms should share a means of passing along the message status. those who don't wnat to see it can turn it off with ?status=off.

The Ascii layout is as follows:

Notification Type	Text Representation	Image	Ascii Alternative
NotifyType.INFO	info		[i]
NotifyType.SUCCESS	success		[+]
NotifyType.WARNING	warning		[~]
NotifyType.FAILURE	failure		[!]

The following systems have been detected to not properly pass along the status:

• SignalAPI
• ... still need to iterate over the /plugins and get remaining impacted plugins
