[bugfix] remove lru_cache from botMayEdit method

- lru_cache keeps all page references and leads to exhausting memory usage if a lot of pages are loaded. See also https://bugs.python.org/issue19859 Replace lru_cache by the Page attribute "_bot_may_edit" - delete this cache attribute if a page is reloaded with Page.get(force) from life wiki because the content can have been changed
