Added AutoCompletion of Javascript statements when the Tab key is pressed.
This version includes a first draft of the signs module and the arrows module.
Right now menu-style signs can be created (but not saved/loaded yet)
Sample signs are provided for changing the time of day and for choosing Arrow types.
A first draft of the arrows module is also included. This includes 4 new types of arrow...

/js arrows.explosive()
Makes the player's arrows explode on impact.

/js arrows.teleport()
Makes the player teleport to where the arrow landed

/js arrows.lightning()
Makes lightning strike where the arrow landed.

/js arrows.flourish()
Makes a tree grow where the arrow landed.

/js arrows.sign()
If the player is pointing at a sign then it's turned into a menu-sign which players can use to choose an arrow type.

Saving and loading of menu-signs and player's chosen arrow type is not yet loaded or saved.
