2.1.3Fixed the bug in hiding card duplicates algorithm.
Previously the card was considered duplicate when there were more recently released
namesake.
This worked ok except when you search by set. In this case many cards from the set are
not shown at all because there is a more recent version in another set.
The fix is to check existence of a more recent version only among other cards that
comply to the search criterion.
2.1.2In search string curly braces
{,
} are considered normal word characters
As a result a query
ManaCost: \{W\} yields only the cards with ManaCost
exactly equal to

instead of cards like

,

and etc.
To control the precision of the query use
* or
?. The query
ManaCost: *\{W\}* will return all cards that contain

in their
mana cost.
Consider a query
ManaCost: \{B\}???It returns cards with mana cost beginning with

and containing 1 more
mana symbol after:

,

, and etc.
