confusing logical-and with bitwise-and in scan_v3.cpp

[kidmin]

Maybe the mistake has been corrected in later versions, but...

EmoCheck/emocheck/modules/scan_v3.cpp

Line 22 in 58677d7

if (directory_name != "." & directory_name != "..") {

The & (bitwise-and) should be && (logical-and) in the context.
