Create a Plugins menu
=====================
This plugin creates a **Plugins** menu and adds an item to it for each active
plugin. Selecting these menu items will bring up a short **About Plugin** dialog
with the details of the plugin. In some circumstances a submenu will be created
instead and an 'About' menu entry will be created in this.
INI files and the Properties Dialog.
------------------------------------
If a file exists in the plugins directory with the same file name as the plugin
but with a .ini extension instead of .py, then a **Properties** item will be
created in a submenu. Selecting this item will pop up a Properties Dialog which
will allow the contents of this file to be edited.
The .ini file should be formated for use by the python ConfigParser class.
Special Methods
---------------
Certain methods defined at the top level are considered special.
**cmd_XZY**
If a method is defined at the module level with a name of the form
**cmd_XZY** then a menu item **XZY** will be created which will invoke
**cmd_XZY** when it is selected. These menus will appear in a sub menu.
**applyConfiguration**
If this method exists then it will be called whenever
**topLevelMenu**
This method, if it exists, will be called when the user clicks on the plugin
name in the plugins menu (or the **About** item in its submenu), but only if
the plugin was loaded properly and registered with g.plugin_signon.
Special Variable Names
----------------------
Some names defined at the top level have special significance.
**__plugin_name__**
This will be used to define the name of the plugin and will be used
as a label for its menu entry.
**__plugin_priority__**
Plugins can also attempt to select the order they will appear in the menu by
defining a __plugin_prioriy__. The menu will be created with the highest
priority items first. This behavior is not guaranteed since other plugins
can define any priority. This priority does not affect the order of calling
handlers.
To change the order select a number outside the range 0-200 since this range
is used internally for sorting alphabetically. Properties and INI files.

# 1.4 EKR: Check at runtime to make sure that the plugin has been loaded
# before calling topLevelMenu function.
# 1.5 EKR:
# - Check for ImportError directly in Plugin.__init__.
# Alas, this can not report import problems without more work.
# This _really_ should be done, but it will have to wait.
# As a workaround, plugins_manager.py now has an init method and reports its
# own import problems.
# 1.6 Paul Paterson:
# - Add support for plugin groups. Each group gets its own sub menu now
# - Set __plugin_group__ to "Core"
# 1.7 EKR: Set default version in Plugin.__init__ so plugins without version
# still appear in plugin menu.
# 1.8 Paul Paterson: Changed the names in the plugin menu to remove at_, mod_
# and capitalized.
# 1.9 Paul Paterson:
# - Refactored to allow dynamically adding plugins to the menu after initial
# load
# - Reformatted menu items for cmd_ThisIsIt to be "This Is It"
# 1.10 EKR: Removed the g.app.dialog hack.
# 1.11 EKR: Added event arg to cmd_callback. This was causing crashes in
# several plugins.
# 1.12 EKR: Fixed bug per
# http://sourceforge.net/forum/message.php?msg_id=3810157
# 1.13 EKR:
# - Always Plugin.name and Plugin.realname for use by createPluginsMenu.
# - Add plugins to Plugins menu *only* if they have been explicitly enabled.
# This solves the HTTP mystery: HTTP was being imported by mod_scripting
# plugin.
# 1.14 EKR: Added init function.
# 1.15 plumloco: Separated out the gui elements of the 'properties' and
# 'about' dialogs to make the plugin gui independant.
# 1.16 bobjack:
# - Added 'Text to HTML' and 'RST to HTML' buttons to TkScrolledMessageDialog.
# - Converted docstring to RST.
# 2.0 EKR: Now works with Python 3.x.
