Subject: [PATCH] cardconv updated. png images converted from gifs by IM
 resulted in an indexed png format. This lead to Problems with tranparency,
 especially with ganijfa and hanafuda cardsets. To circumvent these problems
 IM had to be advised to produce 32 bit mode rgba format. affects android apk
 build process only.
