[fpc-pascal] Compiling android example

[Felipe Monteiro de Carvalho]

It might be useful to know that I rebased my trunk to a new project,
systeminfo4android which is a simple program that I wrote to help me
at work. It calculates the reported screen diameter in inches, as well
as all data from DisplayMetrics.

I documented this here: http://wiki.lazarus.freepascal.org/Android4Pascal

Updating (if desired, since not much changed) is easy, just copy the
*pas and *java files to your project. The java ones of course need to
have some stuff renamed as usual.
