The new version of Wallabag (2) was rewrote completly, and the sharer changed.
This keeps the old Wallabag v1 sharer, for people still using it, and adds a new one for Wallabag v2.
The old sharer for wallabag v1 is renamed to 'wallabag v1' (instead of 'wallabag').
If an RSS feed title contains double quotes, this prematurely terminates the subject line and prohibits the URL to be added to the email body when using Share->Email.
Replace urlencode() with rawurlencode() for all transform functions.
Previously, the share page can handle only a limited number of shares and only one of each type.
Now the configuration has been change to be more flexible and allows an unlimited number of shares.
The share description is located in an array and the share configuration is stored along with the
user configuration.
Note: I tried to include the specific javascript code in a separate file but I did not succeded to
import it.
