Handle situations (user diconnected ?) where Google just answers with nil data.
Revert commit b4f50292219db9601a7483c8d31cb7e6fa2fa077 as it was a false problem (only appeared in my virtual machine), and it was a waste of space : https://twitter.com/shadowbottle/status/309378838322872320
Merge pull request #154 from barijaona/bugfixes

Two bugfixes : handle situations with an expired Google token after computer sleep, and spacing on articles' list.
Copying of the plugin icon was forgotten. Moved application icon into Resources folder.
Add a preference which spot updates on articles previously read (they appear with a green dot in Report and Condensed layouts).

Enlarge text labels to make automatic generation of localized nibs easier.
Regenerate english version of GeneratePreferences.strings

(Run ibtool --generate-strings-file lproj/en.lproj/GeneralPreferences.strings lproj/en.lproj/GeneralPreferences.nib,
then make sure the generated file is UTF-8 encoded)
Refactor the french GeneralPreferences.strings, then regenerate the corresponding GeneralPreferences.nib using the english version as a model.

(Adapt the .strings, then run
ibtool --strings-file lproj/fr.lproj/GeneralPreferences.strings --write lproj/fr.lproj/GeneralPreferences.nib lproj/en.lproj/GeneralPreferences.nib
)
Perform the GeneralPreferences.strings and GeneralPreferences.nib rebuild for languages other than French and English.

Hopefully, bindings for a few elements were also corrected in the process.
