Update to v20141016

(\ /)
(….…) Bunny met changes he wanted more than a 1-ri long carrot.
(> <)

1. Fix screenshots left raw if they were put into the current directory.
2. Fixed loading of external files that have v[number] after the episode
   number. Implemented debugging for that part of code.
3. Fix journal entries which VIDEOFILES variable contained files with
   single quote in their names and which couldn’t load properly because
   of that.
4. Improve util-linux version check.
5. Make error message about an empty folder hinting for a possible
   mistake which some weird patterns in --subfolders could lead to.
6. --mplayer-opts is now cumulative.
7. Add .mka to the tracks extensions.
8. The keyword is now can be a pattern!
   -f switch that tells watch.sh to treat keyword as a fixed string, may
   be used to use ‘.’ ‘*’ and ‘|’ in the pattern.
   Also entries from your journal will become invalid after update, this
   is normal, there’s just two new variables, and one of them
   required to be present.
9. Arrow keys are now working in the menu! So selecting an item is as
   simple as pressing “up” and “down”. The update introduces two new
   options for used-defined keys to increment and decrement the number
   besides the arrow keys. They are --my-increment and --my-decrement.
10. Finally a proper README.md and wiki on Github.
11. Other little changes, code cleanup and bugfixes.
