fixing bug #1781 (installing modes/tools on Win)
changes a rename/move to a copy and delete
pulls the delete step out one level so that we can unload the temp
'newContrib' first, since having it loaded was locking the files from
being renamed/removed on Windows (somewhat erratically).

A bit slower than before but should work a heck of a lot more
often for Windows users.

#1681
Syntax highlighting with / bug low
file :PdeKeywords.java  
function:markTokensImpl(...) 

Explanation:

During the scanning of the line to check if the Token belongs to
Processing Syntax ,When my current character is "/" , we check if the
next character(if any) is "*" or "/" , and we do then an increment of
the scanning index , so in this case , and if the next character in an
alphabet we don’t have a problem , but if it is " " (a space) , the loss
of this character will make the  lastKeyword scan index incorrect , so
we get this problem  of highlighting . To solve it, we check before
incrementing the index, if the next character is " ", so we don’t
increment.

Result and Test:
The example mouseX/ mouseY  highlight the two PDE keyword and  
 the fix  http://processing.org/bugs/bugzilla/609.html
//*
println("1");
/*/
println("2");
//*/
still working .So i think this fix works
