- No longer get JDBC driver using `Class.forName`.
- Remove System.out and System.err and replace them with call to SLF4J for logging and logback has a backend with currently only a development debug configuration that log to STDOUT.
- Use MariaDB JDBC driver.
- Make code tolerant to database connection issue (log error in log and display error message to user).
- Get d3.js using HTTPS (avoid a redirection).
- Set default project using the first one in project list rather than hardcoded ASM.
-  Use Servlet version 3.1.0 instead of 4.0.1 as we target Jetty 9.4 that only support servlet 3.1.0.
