Add tip to explain order of digits in cage

[GoogleCodeExporter]

Users unfamiliar with MathDoku rules often do not understand that the result 
"2/" can be achieved as "2 / 1" as well as "1 / 2".

Intended for:
 * Users who are not yet familiar with the rules of MathDoku.

Conditions for displaying:
 * The "Do not show again" checkbox for this tip is not checked.
 * The user clicks a cell with operator "/" or "-".

Optional functionality:
 * User who have already solved a game will be treated as an experienced player who already know the rules of MathDoku. The "Do not show again" checkbox for this tip will be checked when upgrading to this release.

Has been implemented in version 1.96. 

Tips for testing: During file conversion it is determined whether the user 
already has solved at least two games. If so, the user is treated as a user who 
already knows the rules of MathDoku and the tip will not be displayed.

Tested on Revision 224:

See general comment about the "Do not show again" checkbox on Issue 90.

My observations:
1) I managed to bring this dialog up twice when playing the game by:
  a) Make sure maybe mode is on.
  b) In a cell where I wanted to mark "1" & "3", I pressed both keys in quick succession. The tip dialog appeared twice i.e. I had to close both to get back to the board.
2) The example says "The entire grid below is therefore valid", but actually 
shows the same order of values (low->high). To make the point, would it not be 
better to show an example with the values both ways round e.g. "2/=4,2" & 
"3/=1,3" or even more extreme: "3/=1,3" & "3/=3,1"?
3) The dialog does not fit on the screen on most devices without scrolling (see 
screenshot from Nexus 4). Would it be worth reducing the size of the graphic so 
that the tip can fit on a screen without having to scroll?

Resolved in r227:
1) Multiple tip dialogs are now prevented
2) Image and text have been changed.
3) Image size has been reduced. Did not test on xhpdi screens as my emulators 
keep crashing.

Tested Revision 227:
1) Only a single dialog is shown, regardless of how quickly the numbers are 
pressed
2) Personally, I think the example is much clearer and will hopefully get the 
point across.
3) The new screenshots are much clearer (both size and newspaper theme)
