Align BTextview value of paste count inside settings to center

[scythx]

It's not in center, so i'd suggest to centerized the value.

Hmmm... it's centered for me... Do you test against the latest commit in the repo?

Oh, I see. The "100" is centered, a single digit number isn't. I'll look into, but it may be an issue with BTextControl. It's already told to align center...
