Add an option to use bold text for feeds/folders with unread items

[ao2]

This allows to have back the old 1.10 look of the feed list, where
feeds/folders with unread items had bold text.

As highlighted in #29 some
users prefer the old look because it suits better their environment,
however liferea does not support it "publicly" anymore, the option is
provided only for backward compatibility.

Users who wanted the old behavior have to set the GSettings value
"feedlist-unread-items-bold" to true by themselves, using dconf-editor
or with a command like the following:

$ gsettings set net.sf.liferea feedlist-unread-items-bold true

For what it's worth: I've been running with this patched into the Debian package since October 14 and have not found any problems, glitches or bugs with it.

I personally would be very thankful if this PR could be merged (and hopefully make into the next Debian release on time).

I hope this patch will get into the next release, it significantly improves readability and processing of feeds, especially if you have a lot of feeds in a folder.

@lwindolf any comments about this?

Thanks,

*bump* I'd really like to see this PR merged, since I assumed the non-bold unread feeds were a bug.

Sad that this didn't make it into 1.12-rc3 release :(

Tried a plugin approach in pull request #532 that mught be more acceptable..

[ao2]

@yaneti thanks, I haven't tested it yet but an external plugin looks acceptable to me too as a solution, if the core patch gets rejected.

Thanks,
Antonio

[lwindolf]

As @yaneti contributed a plugin which works fine, I'm closing this PR. I hope everyone is ok with it!

[ao2]

OK, I tested the plugin and it work really well, thanks @yaneti.

@lwindolf if you could tag an rc4, distributions will update their packages and more users will benefit from the plugin.

Thanks,
Antonio

@ao2 I'm aiming for the 1.12.0 actually :-)
