Prefetch war noch nicht vollstaendig implementiert und sollte es nun sein.

Mode: typeAheadPedantic
TypeAhead.php: Implemented new parameter  TYPEAHEAD_API_PREFETCH.
Ldap.php: add new mode MODE_LDAP_PREFETCH
AbstractBuildForm.php: If FE_TYPEAHEAD_PEDANTIC is specified, add attribute DATA_TYPEAHEAD_PEDANTIC,'true'

Implementation started - code is broken

#3431 / typeAheadSql: columnname 'key' is a reserverd SQL statement - replace by 'id'. Additional the parametername 'typeAheadLdapKeyPrintf' renamed to 'typeAheadLdapIdPrintf'.
typeAhead.php: fixed typo.
TypeAhead.php: introduced new mapping from 'id' (SQL) to 'key' (API).
AbstractBuildForm.php: Constant renamed.
Database.php: update function makeArrayDict() to reflect name mapping.

Fix #3419 / typeAheadSql: Array mit nur einer Spalte oder andere KeyNamen als key / value werden nicht korrekt behandelt.
TypeAhead.php: Added detection of missing ... LIMIT in FE_TYPEAHEAD_SQL. Make resultset always a two column array with columns key/value.
Database.php: Added function hasLimit() and makeArrayDict().

Typeahead (#3369): Parameternames has changed, configuration is possible on the Form and on the FormElement.
typeahead.php: if there is an exception, the message body is sent as regular 'content' for the dropdownbox. At the moment this is the only way to transmit any error messages.
Ldap.php: missing FE_TYPEAHEAD_LDAP_KEY_PRINTF, FE_TYPEAHEAD_LDAP_VALUE_PRINTF will be substituted by the other. If both missing, an exception is thrown.

Ldap.php: fixed implementation errors of first run.
AbstractBuildForm.php: set defaults for limit and minlegth. Implement function checkSqlAppendLimit()

TypeAhead.php: Reformat of various constants. Hard coded LDAP query replaced by one submitted via SIP.

Ldap.php: New class to manage LDAP access.
AbstractBuildForm.php: Add attributes DATA_TYPEAHEAD_LIMIT, DATA_TYPEAHEAD_MINLENGTH. Parsing of FormElement.parameter.typeahead* parameter.
