Aggiornamento per Android 15

When playing 301, 501, 701 or 901, a scoreboard is now available. In addition, you have access to your statistics while playing a leg.
Fixed an error when calculation checkout quotes.

Many of you have asked for it, now it is finally possible: You can now also store your very own finishes in the checkout table and practice them in training!

New Checkouts:
51 =  15 D18
54 = 18 D18
55 = 19 D18
56 = 20 D18
81 = T15 D18

Minor Bugfixes

In arithmetic training it is possible now to configure the number range that should be trained. (Thx to Mario for this feature request!)
Added possible checkouts:
71 = T17 D10
72 = T20 D6
74 = T18 D10
77 = T15 D16
82 = T20 D11
121 = T20 SB D18
122 = T20 T10 D16
123 = T20 T17 D6
126 = T20 T10 D18
128 = T20 T20 D4
129 = T20 T19 D6

501 has been added. Many different settings are possible, for example, you can start with more or fewer points. It is also possible to play with any number of players.
Added some new checkout possibilities: 
65=T19+D4
66=T14+D12

New game Bob's 27 -> train your double hit rate under pressure!

Minor improvements and fixes
Added animations to Around the clock

New game "Around the clock"!
In addition to mental training, you can now also practice your accuracy on the whole board. You can choose from dozens of variations, for example whether you want to throw at all segments or perhaps only train doubles. The best thing about it: You can train with any number of players. This makes the training even more fun and you get better in the group.

The checkout table can now also be zoomed on iPhones.
If you edit a finish in the checkout table, you can easily skip to the next or previous finish.
Some other small enhancements.

Checkout table can now be filtered and on the iPad also be zoomed 
Landscape orientation is now supported on the iPad
