[Kimchi-devel] [PATCH] Detect and enable help page from plugins tabs

[Rodrigo Trujillo]

Kimchi is currently not able to configure and open help pages of any
plugin tab. This patch fixes this problem and removes the HELP button
if the plugin does not have a help configured properly.

Help pages for a plugin tab follow same Kimchi system:
   - html help file should have the same name of plugin html tab file
   - html files should be in plugin's " ui/pages/help/<LANG> " path
   - plugin should add following lines to <PLUGIN_NAME>.conf:
        * [/help]
        * tools.staticdir.on = True
        * tools.nocache.on = True
   - plugins should add a <help> element with tab help html name in
     "ui/config/tab-ext.xml", for each configured tab. If this
     element does not exist, 'Help' will be disabled
