sqlite3 integration

Hi all.

I recently tested whether OpenFire can use SQLite as a database. It seems it's quite easy to set up:

1. Get sqlite lib at https://bitbucket.org/xerial/sqlite-jdbc/downloads/sqlite-jdbc-3.7.2.jar and put it to /opt/openfire/lib.

2. Create database:

sqlite3 /path/to/openfire.db < /opt/openfire/resources/database/openfire_postgresql.sql

This will result in:

Error: near line 86: near "CONSTRAINT": syntax error

To fix this you should connect to the database and do:

pragma foreign_keys=on;droptable ofRosterGroups;CREATETABLE "ofRosterGroups" (  rosterID integerNOTNULL,  rank integernotnull,  groupName VARCHAR(255) notnull,  constraint ofRosterGroups_pk primarykey (rosterID, rank),  foreignkey (rosterID) references ofRoster(rosterID)
);

3. When configuring service select:

• Database Driver Preset: PostgreSQL
• JDBC driver class: org.sqlite.JDBC
• Database URL: jdbc:sqlite:/path/to/openfire.sqlite

The only bad thing I saw yet about this set up is:
