Escape special characters in silent install file and sample XML files (6431990)

Special characters must be escaped (preceded with a back slash) in the silent installation file. Also, after installation, if you want to run the Liberty SSO or SPI samples, you need to edit the metadata XML files and escape the special characters before loading them using the amadmin command line tool.

WORKAROUND: Replace & with \&, or a space with \ . For example, rather than defining the INST_ORGANIZATION parameter in the silent installation file as INST_ORGANIZATION=dc=a b & c, use INST_ORGANIZATION=dc=a\ b\ \&\ c.
