commander: settings dialog, project files, symbols, icons

Added settings to the plugin configuration dialog, allowing you to control the
display of project files, symbols in the command panel and the size of the
command panel. Added the ability to recursively search for project files using
the installed file pattern. Added the ability to search for symbols. Added
display of icons, for files and menus the icons are fixed, for symbols (tags)
they are different depending on the type of symbol.
