Added /tmp/rssitems file to monitor new rss
This is mega-patch (костыль), it's working only if applied rules for
creating file /tmp/rssitems when new rss is ready :)
So, I've managed to do it by editing ACTUAL sources of canto-curses and
adding os.system("echo 'NewItem' > /tmp/rssitems").
Now I need whether add this to git (which is bad, because it's an
updating app and located in /lib or whatever) or add line to my eal
script which will sed/grep/awk/smth. else with the file after package
canto-curses is installed.
