FlashCards updates

Although the biggest changes are under the hood (merged major changes from the parent project), but there some visible changes too that are interesting.

• Dictionary lookup page is now easier to use, by showing less dictionaries at first, the most frequently used ones.
• Adjusted texts. Hopefully the messages are clearer and easier to understand.

Finally, there is a wizard for users who login for the first time. Wait a minute, wasn’t this already announced? Yes it was, and then a next post said ‘it is in the pipeline’, so to set the record straight, yes, there is a wizard, there has been for a while.
