Add trim feature

[dukio]

Hi, is there any way to trim each line of the output currently? if no... I think it would be really useful to add as a feature 😁

Here's an example, I'm getting diffs like this:

(changed)                   Notebook Acer Travelmate 4070
(into)                   Notebook Acer Travelmate 4070 con Intel Centrino
(changed)                     80 €
(into)                     65 €

As you can see there's a lot of useless spaces at the beginning of each line that makes the diff harder to read on notifications (like in telegram)... so it would be great if I could get rid of those!

@dukio I was looking for a solution for that as well and found out that you can trim those whitespaces altogether from the text, using "Extract text" regex, like so:

/^[\s\t\r\n ]*(.*?)[\s\t ]*$/im

It will get rid of any whitespace at the beginning of a line and the end of a line.

Important note, it will work when a new change appears - changedetection somehow caches old output with spaces. Either wait for the next change or clear history to see the trimmed result.

Thanks! This works :D
