Introduce haptic feedback

[esai256]

Hi!
I added a setting to enable haptic feedback every time you increased or decreased a counter.

Context

I use the BetterCounter for knitting, more specifically for counting my rows. It happened to me some times, that I pressed too long, or moved away from the button, so the button did not actually trigger without me noticing.
Then, when I noticed, that I sometimes missed it, I became paranoid about whether I pressed. Increasing a row sometimes happens within a minute, so sadly the time display alone won't help.
Having haptic confirmation would help me a lot, I think.

Changes

• I added an entry "isHapticFeedbackEnabled" to the Repository to store the setting.
• I addded the respective switch to the settings activity in a new section "Behavior".
• The switch default setting is "off", therefore the default behavior doesn't change.
• I added the haptic feedback in the EntryViewHolder. I'm unsure, whether this is the right place, as most logic happens in the MainActivity, but felt this was more UI-related and therefore it might be good here.

I am not confident in Java and/or Kotlin, so if I'm missing conventions, I'm happy to learn.

I think the feature makes sense and the code looks good.

Since we don't have any other "behavior" settings, I would maybe change the strings so that "Haptic feedack" is the title and add a simple description like "Vibrate when changing a counter" as the text next to the toggle (also because not everybody knows what haptic means).

I haven't been able to try the app with the change yet, but will do so after the holidays :)

I didn't think about knitting as a use case for the app, I'm happy it helps for that 😄
