* use python2.4/2.5 compatible import of ElementTree

* catch Popen() calls to missing VCS binaries
* test.py should only test installed backends

+ImportError: No module named elementtree
+
+
+Looking into ElementTree, I found their webpage:
+http://effbot.org/zone/element-index.htm
+
+  It’s common practice to import ElementTree under an alias, both to
+  minimize typing, and to make it easier to switch between different
+  implementations:
+
+  $ python
+  >>> import elementtree.ElementTree as ET
+  >>> import cElementTree as ET
+  >>> import lxml.etree as ET
+  >>> import xml.etree.ElementTree as ET # Python 2.5
+
+Using new import style, fall back to old if that fails.
