Corrected hxc-evolution so that pokemon with branched evolutions (i.e. eevee) will be fully included. As a result, altered hxc-evolution to return a list of hashes, one per evolution.

rlm@1 16 * @note We assume that your system has inttypes.h. If your system
rlm@1 17 * doesn't have inttypes.h, you have to typedef uint32_t and uint64_t,
rlm@1 18 * and you have to define PRIu64 and PRIx64 in this file as follows:
rlm@1 19 * @verbatim
rlm@1 20 typedef unsigned int uint32_t
rlm@1 21 typedef unsigned long long uint64_t
rlm@1 22 #define PRIu64 "llu"
rlm@1 23 #define PRIx64 "llx"
rlm@1 24 @endverbatim
rlm@1 25 * uint32_t must be exactly 32-bit unsigned integer type (no more, no
rlm@1 26 * less), and uint64_t must be exactly 64-bit unsigned integer type.
rlm@1 27 * PRIu64 and PRIx64 are used for printf function to print 64-bit
rlm@1 28 * unsigned int and 64-bit unsigned int in hexadecimal format.
