--------------------------------------
HI [~zhuqi], thanks for your review and advice! Submit 003 patch for resolve
these problem.
{code:java}
1. We'd better add an enable flag to trigger this besides null check.
{code}
I think enable flag is redundant. And i don't add the flag in 003.
{code:java}
2. We should also add the new conf in core-default.xml.
{code}
Done in 003.
{code:java}
3. We should add some doc for getTrashHome method consistent with
getHomeDirectory.
{code}
Done in 003.
> Add a configuration item for special trash dir
