Additional language on dialpad

[Belyavin]

Fixes FossifyOrg/Phone#47

[Aga-C]

Letters in both languages should be centered (e.g. 3 looks really bad).

@Aga-C also the height of the lowest row of keys is different, which looks weird.

And also # and * are not vertically aligned with the 0, but this is also the case on the master branch. Might be a different PR?

[Belyavin]

I've changed the string to a common one, and aligned the text to the center. I also aligned * and # to 0, though I'm not sure if it became better, need you opinion on this.

Hi, are we waiting for something before merging?

[Aga-C]

@Belyavin You have to wait for the final review from Naveen.

I also aligned * and # to 0, though I'm not sure if it became better, need you opinion on this.

@Belyavin indeed * and # look better when centered, I reverted that change.
