Fixed bug#7337 - AJAX Error on new Phone Ticket on IIS when using JSON::XS
fixup! Fixed bug#7337 - AJAX Error on new Phone Ticket on IIS when using JSON::XS
Fixed: Datepicker localization data could not be found! when choosing French canadian language (bug#9962).
Follow-up for bug#9962: make JSON handling more robust and simple.
Simplified code.

On Windows, we EITHER have Apache/CGI OR we have IIS/PerlEx.
Meaning we NEVER have mod_perl (because it's instable).
This also means we will never want to show the installed
Apache modules on Windows and any installation issues with those
because this is not relevant.
Code improvements.

Removed Charset atttribute of _ConvertFrom and _ConvertTo
because the internal charset is always utf8.

Also renamed the charset variable to 'SourceCharset' so it
aligns better with the configuration options and variables
used in CustomerUser/LDAP.pm

Removed unused _ConvertFrom in Auth/LDAP.pm.
WIP CustomerUser improvements for DBs with different charsets.
