[Qgis-developer] plugin installer update

[Borys Jurgiel]

Good Morning List, 
The updated plugin installer is available for downloading.
I'll be glad to read any opinions about the new tab. 

CHANGELOG:
1) The list of URLs excluded from proxy is now respected.

2) Checking for updates on startup can be performed every several days now.
  
3) The new optional xml tag <experimental> is now supported. The value can be 
True or False. So now plugins can be either: official, contributed or 
experimental. The last one is designed for concepts and sandbox tools and it's 
at the author's / repo admin's discretion. See the third tab for more details.
I believe it's more reliable than a detailed tag: 
experimental/unstable/testing/stable/foo/blahblah/superstable 
what would be unclear and never up-to-date. Does everybody like this way? If yes 
I'll ask Gary for adding it to the central contributed repository. If no, we can 
discuss something more detailed.

4) Better support for the <qgis_minimum_version> and <qgis_maximum_version> 
tags. Note that the <qgis_minimum_version> is required while the 
<qgis_maximum_version> is optional and even not recommended. In most cases this 
tag is unnecessary and confusing, so please use it only if needed. This tag is 
only present in the repository xml, not in the plugin __init__.py file.  

A TIP: If you have written a plugin designed for BOTH QGISes 0.x and 1.x (like 
the installer itself), you need to set the both <qgis_minimum_version> and 
<qgis_maximum_version> tags. Otherwise the plugin is only visible in the QGIS 
line matching the <qgis_minimum_version> tag (it doesn't cross the 0.x/1.x api 
barrier).

5) Some small fixes: updated url of the repository of Faunalia, better trimmed 
xml tag values and user input strings etc.

Regards,
B.
