v0.6.8

This is mostly a bugfix release, with following changes:

• Fix installation on certain versions of Bash (thank you @old-guru for the bug report)
• Fix re-launching the -install script in another shell (thank you @QuaxEros for the bug report)
• Improve logic for starting the cron service when it's stopped
• Improve spell checking in code and documentation (thank you for the contribution @georgeabr)
• Support building apk packages for OpenWrt

From this release on, I will include both ipk and apk packages for OpenWrt.

To install the apk package (currently only relevant for OpenWrt snapshot builds):

apk --allow-untrusted add geoip-shell_0.6.8-r1.apk

The allow-untrusted option is needed because the package doesn't come from the official OpenWrt packages repository. I am planning to push an updated version to the OpenWrt repo soon'ish but haven't had the time to do this yet.
