Enhanced installation instructions.

Motivation is to make use these same instructions also as INSTALL.rst
in project root (#1779).

Changes done now:
- Drop references to One Click Installer (only worked on XP) and
  already removed non-standard install.py script (#1753).
- List using pip as the first and most recommended installation approach.
- General clean-up.
Removed info about libdoc etc. entry points from installation instructions.

These entry points are nevertheless explained in detail under the doc
of each tool. The goal is to simplify installation instructions as
discussed in #1779.

xml atests: fixed typo and argument name
XML: Fix handling elements w/o namespace inside elements w/ ns.

The problem occurred when namespace prefixes in Clarck notation were
stripped (default behavior) and affected both the standard etree and
lxml modes.

After the fix elements w/o ns inside elements w/ ns get `xmlns=""`
when using the standard etree. When using lxml, namespace prefixes are
preserved correctly. These fixes resolve #1784.
Update README.rst
