1) Made getVariables and evalBlock methods in PHPDBGInterface synchronized (At least for evalBlock this is absolutely necessary for eclipse 3.2 compatibility).
2) getVariables method returns an empty vector if socket is closed (avoiding exception).
3) updateStackFrameList improved to avoid rebuild of variables view when stepping through the current php file.
4) getAdapter in PHPDebugTarget calls super.getAdapter (for eclipse 3.2 compatibility)
5) hasVariables in PHPStackFrame return always true (for eclipse 3.2 compatibility)
6) Removed second sending of RESUME event in stepInto and stepOver (in PHPStackFrame).
7) getStackFrames (in PHPThread) returns the stackframes only if in suspended state (for eclipse 3.2 compatibility).
8) PHPWatchExpressionDelegateCode beautifying.
