[Tikzdevice-bugs] maintainer field in DESCRIPTION file

[Stefan Theussl]

Dear tikzdevice maintainers,

Due to a ':' in the maintainer field of the DESCRIPTION file in the 
tikzDevice package we receive emails containing various 'FROM' addresses 
in the mail header. This happens every time when you submit packages to 
CRAN. Thus, could you please avoid ':' in the maintainer field?

Thanks,
Stefan
