Clang: Add -isystem flag support everywhere

In GNU.cmake, -isystem is not used if APPLE is set. However, Clang has
pretty much always supported -isystem, so we should always use it.

In the future, GNU.cmake should do a version check to see if -isystem is
supported.

UseJava.cmake: require explicit request to include jars

Modify add_jar to (partly) use cmake_parse_arguments, and to require
using the named argument list INCLUDE_JARS to specify jar files (or jar
targets) to use as dependencies when creating a jar. This preserves the
ability to have such, while restoring the historic behavior that jar
files listed as sources are ignored. (The code now explicitly ignores
them, however, rather than adding them to an unused local variable, so
that it is more clear that nothing is being done with them.)

Modules/readme.txt: switch from "XXX" to "Xxx"

Using XXX as name of the package is ambiguous, since it can be
interpreted as "ALLUPPERCASE" and also as "ExactCase (if the name
is already ALLUPPERCASE)".
After extensive discussion there is the conclusion that ExactCase
is intended, so using a CamelCased name makes that more obvious.

Modules/readme.txt: make lines a bit shorter for easier readability

This patch doesn't make them 79 characters long, but at least gets rid
of really long lines.  While at it, fix spelling of "relevant".
