NullPointerException if board.bootloader.path not defined

[GoogleCodeExporter]

What steps will reproduce the problem?

Create a board definition in boards.txt without a bootloader definition.

What is the expected output? What do you see instead?

The new Leonardo support code throws a NullPointerException.

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?

Arduino 1.0.1 on Linux.

Please provide any additional information below.

This line (AvrdudeUploader.java, line 88), dereferences the result of 
boardPreferences.get("bootloader.path") without first checking if it is null.

    if (boardPreferences.get("bootloader.path").equals("caterina")) {

There are at least 2 places where the string's equals() method is called 
without checking for null.

As a workaround, and board which doesn't use a bootloader will need to define a 
dummy "bootloader.path" to avoid this bug.

Good catch.  I'll fix this for the next release.
