initial release of myreadings package

Hi,

This is my first attempt to bring MyReadings package to SynoCommunity/spksrc

MyReadings is a web interface for Calibre software, which allows you to read ebooks from tablets, PCs, Macs, smartphones and other media devices.

It's similar to the COPS package already present in spksrc. These files are mainly modifications from the original spksrc COPS files.

Thanks,
