#218 gemrb hangs if config contains lines with whitespace only

[Jarda Benkovsky]

mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fe6ffa84000
read(3, "################################"..., 4096) = 4096
lseek(3, -2150, SEEK_CUR) = 1946
read(3, "GameType=how\n\n##################"..., 4096) = 4096
lseek(3, 6042, SEEK_SET) = 6042
lseek(3, 6042, SEEK_SET) = 6042
.....

also the config search code uses PathJoin which nowadays does too much stuff behind the scenes, would be better to change to use PathAppend.

Some details:

It'll get stuck in an infinite loop of reading one character and going back one character, with the 'continue' here:

if (fscanf( config, "%64[^= ] = %[^\r\n]%*[\r\n]", name, value )!=2)
continue;

also downplay the errors for separate cfg files, print error only in the end

Should be fixed in master
