Random changes and tweaks + new example db with working "say" verb:

* Hacky fixed scrolling bug when showing editor pane
* Added client-side 'clear' command
* Tweaked eval and verb context mechanism a bit
* Added the ability to create new verbs on existing objects: edit #<objectid>.<newverbname>
* Added player broadcast function (send message to all other players in the same location)
* Added "say" verb and tweaked other verbs to broadcast in example db
Added some TODO notes so I don't forget
Another small note
Host ace editor locally.
Fix some bugs, closed some TODOs
Wrap moo objects in safe wrapper when in moo code and eval context
Completely rewrote contexts
Many additions to contexts:

* Changed basic object attributes to getters and setters
* Added getters and setters for each object property
* Added callable verbs on context objects
* Added (faked) inheritance for context moo objects
* Added clone and createChild methods for creating new objects
* Added stub methods for still missing functionality
Merge branch 'contextify' into dev
Fixed properties bugs
Basically rewrote everything:

Don't know if it's better or not...
Couldn't accomplish what I wanted too.
New object manipualtion methods and other stuff:

* chparent, rename, updateAlaises (for objects)
* clone and createChild (to create new objects)
* list, tree, and locations (for viewing the db in various ways)
Some work on the README
Updated README
Added player input:

The server can now ask for input from players.
player.input(msg, callback)
Objects can now have global variable names:

New built in attribute called 'var'.
If it's set to something other than null, you can access the object from eval and verb context using $varname.
Updated README
Fixed up example database and some small tweaks.
Merge branch 'dev'
