JayTools v0.5

Version 0.5 of Jay Tools adds a lot of things.

-- Toolbar section in Object mode for those that don't like menus.

-- Updated Add Mirror operator, along with Add Target operator.

This allows you to automatically define a mirror object based on secondary selections or by creating one and automatically assigning it.

-- Made all custom operators context sensitive for current selections

-- Fixed Apply All Modifiers
It now actually works on multiple objects, rather than only the active.
