Not compiling on 32bit linux

[Tony]

I've trie to compile this on 32bit linux specifically Rasbperry Pi OS desktop edition

Around line 5352 the count uint64_t is taken in as a unsigned long int into XGetWindowProperty(), but on 32 bit systems unsigned long int is 32 bits so gcc complains.

Fixed in manually on my side by just chaning count variable to unsigned long int.

I think that pull request #102 fixes this. If it doesn't, please make a new issue.
