bump to include nightly 24
Use grayscale icon, if all feeds are readed
Create CSS file with correct permissions
Used parseInt() because octal literals are deprecated
(should fix #15)
Merge pull request #23 from Infocatcher/fix_save_css

Create CSS file with correct permissions
highlight: make it work for non-ASCII too

The separator chars are hardcoded as JS's \s plus :, *, - for complex
queries. JS does not support non-ASCII character classes, the Sqlite's
simple tokenizer also does not support them, so no more chars should be
required.

closes #21
do not hardcode the possible spaces
Merge pull request #22 from Infocatcher/no_unread_icon

Use grayscale icon if no unread feeds
bump max version in README
