Add better error reporting to DB\IO for query with params

Browse Source 
On error with query with params the query was sent to the server and
if ther query itself is ok but there is a problem with the parameters
a wrong error message ($1 not found) will be returned

Add pg_last_error reporting to catch this too.

Update both error reporting to return not string and prefix combined
but prefix + error string in array

In error return check that both strings are not equal, so we do not
return the same error string twice.

Also default set dbh variable in the PgSQL class to false so it will
skip last error report if there is no dbh set yet.

Bug fix for db query with params debug output. if there are more than 9
entries the $1 of eg $10 is replaced with $1 entry again. Changed to
'#' instead '$' to avoid this.

Other:
ACL\Login: replace EOM with HTML
config.master: replace list() with []
Add single DB tester where we can test single db calls without adding
more to the general test run
