Version 0.1.30

[Greg]

This version starts to look a little different. First, you will be
asked to open a JavaScript file when you start TurKit. Use this
instead of typing the filename into the first line of the previous
dialog. The rest of the information in that dialog now appears in the
new "properties" tab. These properties may be edited at any time, and
will take effect the next time you run.

This version was a little rushed, so I may not have tested everything
thoroughly. Please report any bugs to this list, or directly to me.

----------------------------
change log:

version 0.1.30

- Loading the TurKit jar now asks you to open a JavaScript file.
This JavaScript file will have properties associated with it,
including the AWS access identifiers, and the current mode.
You may set these parameters at any time,
and they will take effect when the JavaScript file is re-executed.

- added menu bar with save, and tools for deleting HITs

- bug fix: reset database now removes HITs regardless of which mode
they were created in
(it knows which mode (sandbox or real) each HIT was created in,
and it switches to that mode before deleting it, for each HIT)

- quitting will ask if you want to save

- bug fix: maxMoney and maxHITs are now adjustable (the values in the
properties file were ignored before)

- "Reset Database" now creates a backup copy of the database before
deleting it.
this file will look something like: mycode.js.database.old2

- there are now 3 different modes:
* "offline" will not let you access MTurk or S3. (Good for using
after an experiment is completed, and all the data is in the database)
* "sandbox" will let you access the MTurk sandbox, and the real S3.
* "real" mode accesses the real MTurk and the real S3.

- Java API change:
- it is now possible to "reinit" the TurKit object with new
parameters,
this function will only re-initialize what is necessary based on
which parameters are different from before.
This features allows the GUI to change the mode without restarting,
in fact, the mode may be changed programmatically using the
"setMode" function in JavaScript

- JavaScript API change:
- added "setMode" function (you probably don't want to use this, it
is mainly used internally)
