two typographical errors -- "textxml.lua" should be "testxml.lua"

[Corin-EU]

In the usage parameter on line 22 of testxml.lua it says "textxml.lua" when it should say "testxml.lua".

      textxml.lua [-print] [-simpletree] [-dom] [-debug] 

In the comments section on line 43 of xmlhandler/tree.lua it says "textxml.lua" when it should say "testxml.lua"

        -- data through 'textxml.lua -simpletree' than to read this)
