[patch-package] Using hash key for local icons instead of increasement key to prevent conflict

[Misaka-0x447f]

This patch issue is submitted by patch-package.

In my project I found that if more than one commit is adding local icon to project, the key of local icon will be conflict in a large scale. So I made this patch:
