2. Removed duplicate of 'make screenshot'
3. Hotkeys (Back & Home) to exit are moved down, to the end of hotkey list
4. Removed outdated comments & not informative comments
- long lines (filenames in 'Document Info') are now splitted in more
human-readable way (by spaces, dots, slashes or some other characters
- see screenshot)
- the selection of fonts in filemanager (key 'F' or 'Aa') looks now more
user-friendly
- fixed too long strings in most menues (TOC, Bookmarks, Fonts...) and
in the popup with the reading progress (called by key 'Menu')
- the position inside the cr-documents (epub, mobi...) now remain nearly
the same after rescaling the document (i.e. changing the font face,
size, boldface and interline distance)
- when you open TOC-menu or Fonts Menu, it highlights the current item
(i.e. current chapter and current fontface).
- i've a bit changed the way to read the battery level values, it might
now work even without Amazon Kindle framework.
