Changes in SuperWaba 5.0

1. Fixed "can't find font" when loading as applet.
2. Avoid 450_11 bound checkings when running on desktop.
3. Added PushButtonGroup?.hidden boolean array to hide some specific buttons.
4. Added IntVector?.pop(int count) to remove elements from the top of the array.
5. fixed problem when popupBlockingModal was called, and an event was generated inside that 'thread', calling another event that invoked a 64bit function. To fix this, i had to completely change the way that values are returned in native functions. So, all native libraries must be changed to conform with it.

The old form of returning values in a native function was:

// for 32bit values
Var v;
v.intValue = ...;
return v;
// for 64bit values
Var v;
v.lower64 = lower64part;
vmGlobals->returnedValue2 = upper64part;
vmGlobals->pushReturnedValue = 2;
Now, the new way of returning values is this one:
// for 32bit values
...
return32(my32bitvalue)
// for 64bit values
...

return64(my64bitvalue)
Check these macros for further information.
6. avoid to load a native library more than once.
7. fixed ByteArrayStream? and ResizeStream? to avoid exploding the buffer size.
8. moved and enhanced ProgressBar? class to waba.ui.
9. added rpm (Redhat Package Manager) support to the SamplesTemplate.xml to deliver superwaba samples or user applications on the new native linux plataform.
10. added File.getCardVolume, to search for the correct place of the expansion card on Windows CE and Pocket PC systems
11. Added a minimal version of the ProgressBar? to waba.ui.
12. added Window.updateScreen method, called by Control.repaintNow (required by SDL).
13. added source code linenumbers in stack traces if debugging information are available. (See the javac '-g' option).
14. fixed new exceptions masking old ones
15. fixed Convert.toLong. The old one was converting "10" to 0.
16. added ListBox?/ComboBox.setOffset to set the horizontal offset from where to draw the items. Can be used to scroll horizontally the listbox. This scroll must be implemented by the user. See superwaba.ext.xplat.unit.SWUnit for an example
17. Now Warp automatically excludes NativeMethods4JDK?.
