import/export channels

Created by Scott Evans
channels conf

First thing, open a terminal and enter the following (from 1.) on the
source PC, then copy the channel.sql to the target PC and then
(from 2.) to import your channels.

1. sqlite3 ~/.local/share/me-tv/me-tv.db ".dump channel" > channel.sql
2. sqlite3 ~/.local/share/me-tv/me-tv.db < channel.sql

1. will export channels, 2. will import channels. Of course, you can
always just copy the database file.

NOTE: ensure that you do not have Me TV running when doing this!
