[Pascal <pascollin@xxxxxxxxx>]

Hi,

I don't know if this is the correct place to announce and post a new 
plugin... but here is mine.

The "Insert snippet" plugin adds a new menu entry "Insert/Text from 
page..." which shows a dialog box where you can enter some page path. 
Then, its content is added to the current edited page.

Current options are :
- remove title (from inserted text)
- increase header level (h1 goes h2, etc)
- insert backlink to source (above and/or under the inserted text)
- show full namespace (by default, only the basename will be shown)
- add some prefix before backlink (something like "**source : **")

It has been tested on zim 0.49 (Ubuntu)

I hope this can be useful.

PS :
- I can provide french gettext messages for translation
- you're welcome to fix incorrect english words in the plugin...

Best regards,
Pascal
