#8 whitespaces after php end-tag

[hampelratte]

(release 1.2.6)
there are whitespaces after the php end-tag ?> in
treecomp.inc.php and doc.inc.php. that causes php to
send a html header to the client and makes problems if
someone (like me ;-) wants to send another one.

Same in release 1.3.0
Whitespaces at the end of each class prepend "\n\n" to the
output. (therefore the output is NOT valid xml anymore!)

Please fix it for next releases.
