Before, the scripts relied unfortunately on the compilation performed by
Eclipse. Now, all the JUnit test cases are compiled all the time before
performing the JUnit validation (i.e. ANT task named `junitValidation`).

This is very useful when getting a stack trace of an exception: without
this option, no method and line information can be provided...so, without
this option, the stack trace becomes pretty useless.
(NOTE: this option increases a little the size of the compiled classes)

in the log output. For that the function UWSToolBox.getParamsMap(...)
had to be modified.

[TAP] Upgrade STIL version + Specify charset encoding for Javadoc generation in all Ant build scripts.

[ALL] Update ANT build scripts to test all existings JUnit tests before compiling. In case of error, the compilation does not complete.

TAP: Execute all JUnit tests before building the TAP library. At any JUnit failure, the build is canceled
+ Update the version number for the generated JARs.
