News for Linux full changelog

- In pref windows, some setting changes (like 'read n items per feed') need the stream to be reloaded, so now we use:
current_feed();
instead of:
update_pixmap_from_opened_stream();
- Fix 'quick feed picker (selected feeds) closes when pointer leaves win area' and implement it as a setting.
- In pref window, disabling screen limits updates win_y and win_w limits on the fly.
- Max options number now set to 128.
- Pref win changes:
- remove 'system' colors buttons
- increase gtk table row spacings
- If gradient bg set, compute text shadow color no longer from bg_color but from gradient.
- Quick feed picker (selected feeds) closes when pointer leaves win area. Plus: quick feed picker opened *also* by Ctrl + mouse right-click.
- Complete RSS 1.0 support (Closes: #688099) and fix/rewrite a few things in feed parser code.
- In tickr_feedparser.c: ending 'n' removed when adding string to XML_DUMP (left when adding string to XML_DUMP_EXTRA).
