fixed ljpost addon
Tried ljpost addon, it doesn't work now. Tried dwpost addon - it works well.
This commit is current dwpost addon with following replaces:
- dw_ to lj_
- dwpost to ljpost
- Dreamwidth to Livejournal
- fixed url (https)
After that it works fine. Crossposts from hubzilla to livejournal works with this commit.
