#18 in names tag keys can not use the symbol ":"

[Alex Breems]

I am happy to use the delicious plugin QuickText 0.2.1 and here is what
I found:
in names tag keys can not use the symbol ":" although the version history it is
permissible

from version history to 0.2.1:
* [+] Valid tag keys
(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890~!
@#$%^&*()_+{}|:?><`-=[]\/.,)

Please fix this bug
