Added some draft code.

Everything is still a mess. I don't have enough time for this.
Made the APN auto-detection code more evolutive.

The goal is to allow to create some custom APN parameters providing rules. We can have new ways of providing APN detection code parameters.
Changed the AutoUpdated code to allow to override the JAD file analysis code and thus retrieve other fields.
Removed some class with a lot of useless stuff and that were apparently decompiled from some existing libraries.
This is actually the removal.
M2MP draft code: Removing the ATCommand class uses
Adding GPS positions filtering code (to only report the interesting ones).
NTP client: Added HELP
Added two console commands:

- uptime to know for how long the program has been running
- version to get the current's program version
Added a (basic) file system management console command.

Available commands are:
- ls
- cd <dir>
- cat <file>
- df
- pwd
- mkdir <dir>
- rm <file or dir>
- wget <url> (<destination file>)
- cp (untested yet)
Added gps testing command. We can test the GPS by typing "gps start" and stop the NMEA stream analysis by typing "gps stop".

Current known bug: After "gps stop", "gps start" doesn't work.
Safequeue: Added new com.cinterion.* namespace support.
NTP client:
* Works: response parsing is OK + conversion to lib time is done
* Relases the DatagramConnection (even when the host is bad)
Time retriever now has a default constructor: NTP time fetching on pool.ntp.org every 24h and every 30 minutes in case of failure.
AutoUpdater: Improved it to be extendable.
GPS handling code: Working fine except that it can't be brought back to life when stopped. I'll investigate this later.
APN autodetection:
* Re-enabled the two default sources for APN auto-detection. This is what should be used for most of the APN auto-detection needs.
AT handling code: Minor changes.
I2C: Added "com.cinterion.*" namespace compatibility.
Demo: Current code is working great. It can be downloaded here:
