boobs.lua: accept parameters

[ruvolof]

Added optional parameter for boobs and butts to send more pictures.

Added extra commit to fix danbooru plugin. It was sending the link to the image, telegram was showing the picture and the the images plugin was resending the image. Now it sends the same information (without the link) and the picture is sent after as the boobs plugin is doing.

When sending multiple images, it should be done using callbacks. A maximum number of images must be set in order users don't flood the bot.

[ruvolof]

Added the limit. Not really clear what you mean about callbacks request.
