Suggestion: Handle data length reductions

[scoman81]

There are two common cases (actually two derivatives of the same case, that just feel different) that would be nice to see handled by this plugin:

1. Full erase. Type some data, Shift+Home, Backspace. This case is when you've typed and then erased everything. The callback doesn't fire, and thus you can't restore state. (I'm using this to trigger a filter on a table of data, and a full erase should restore all data).
2. with captureLength set to 3, type 3 chars, let event fire, then backspace. This case should also be able to let the user restore default state, since 2 characters are considered the same as no characters, but the callback won't fire because the input has only 2 characters.

These are really both the same case: when the data length decreases from over the captureLength setting, to under the captureLength setting.

Adding a 2nd OR clause covers the above cases:
if ((value.length >= options.captureLength && value.toUpperCase() != timer.text)
|| (override && value.length >= options.captureLength)
|| (value.length < options.captureLength && timer.text.length >= options.captureLength))

(Sorry, new to Git, so I apologize if there was some other way I was supposed to submit a suggestion!)

Thanks, this really helped me!

For others:
Replace line line 33/34 with scoman81's code:

if ((value.length >= options.captureLength && value.toUpperCase() != timer.text)
|| (override && value.length >= options.captureLength)
|| (value.length < options.captureLength && timer.text.length >= options.captureLength))

Also, you probably want to set captureLength: 1 to make it trigger when you delete the last character from the textarea.

_scoman81_ Thank you for describing the issue. I've had a few other requests for this fix but they always seemed to describe the issue in a manner that made me think they should just set the _captureLength_ to 1. With your description I was finally able to understand the issue. I'll get your fix in shortly. Thanks.

+1 for this important fix.

This line makes the empty state work.

|| (value.length === 0 && timer.text.length > 0)
