Further tweaks to User-Agent

Follow-up on issue #215 :
- default user agent will now be similar to : `Mozilla/5.0 Vienna/3.0.0`
- browser panes' agent will be similar to : `Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.74.9 (KHTML, like Gecko) Vienna/3.0.0 Safari/537.75.14`

Therefore, the browser panes User-Agent is more similar to Apple Safari's. This way, sites like iMore.com will not nag us anymore that we are using an outdated version of Safari.
Note that the first part of the browser pane User-Agent (which quotes Mozilla/5.0, OS X version and WebKit version) is automatically added by WebKit.
Encode URLs sent to plugins

Solves issue #258

Note that links from browser panes are encoded once, and links from articles list are encoded twice.
So a non-breaking space (byte sequence C2A0) becomes %25C2%25A0

InoReader does not provide the "alternate" information when we fetch a feed. So we need to make use of the "htmlUrl" information provided within the subscriptions list.
