Improve preprocessing of sketches:
 - Better determine which header files are included (not commented out).
 - Remember the original locations of function prototypes to highlight the correct line on error.
Multiple sketch windows.
Avoid library conflicts by only linking in the library whose name matches that of the #included header file.
Easier library discovery and installation ("Add library..." menu item).
Easier board installation ("Add board..." menu item)
Comprehensive board management:
 - Enabled and disabled boards.
 - Dialog for enabling, disabling, adding, deleting, and possibly editing boards.

Guess serial port on the Mac and Linux.
Automatic detection of baud rate for serial monitor (based on the call to Serial.begin() in the current sketch).

Allow uploading of .hex files.
Allow for arbitrary compilation command line arguments.
Find in reference should give same message for missing page as for missing page association.
Test find in reference on libraries.
Change background color while using external editor: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1229567785

Compiler.java
 - Eliminate the need to pass a Target into the compiler by having the Compiler determine the current target (by checking the preferences directly)?
 - Delete the unneeded static functions (for classpath translation, etc.) from the bottom of the file. 

Sketch.java
 - add system-wide include path in preprocess()?
 - should find libraries in the code/ sub-folder of the sketch folder
 - do sketches really need to get built in the applet/ sub-folder when uploading?

PreProcessor.java
 - split write() into writeHeader() and write() as in Processing?
 - add getExtraImports() function instead of having Sketch grab them directly.

Base.java
 - add keywords from libraries to the syntax coloring

Editor.java
 - allow the Board and Serial port to differ across editor windows.  This will require creating a separate instance of the menu for each window, and passing the selections into the sketch when compiling or uploading.
 - send the current board and serial port selections to the sketch (which will forward them to the compiler) when compiling or uploading (this should eliminate the need for the Target class, since the compiler will be able to find the target path and its source files itself)
 - remove references to the Runner and runtime
