Fiji Build: ensure ij.dir is set correctly

Just as with MiniMaven, I'd like to debug things using Eclipse. Now,
I could set the ij.dir explicitly in the debug configuration, or
alternatively the working directory, but why bother?

MiniMaven: write the manifest to target/classes/

... rather than making it on the fly when writing the .jar file. This
is more in line with how Maven works...

MiniMaven: special-case the Fiji Updater

Since the original Fiji Updater checksummed the contents of the .jar
files byte for byte, output from Maven was considered different with
every new build. For this reason, the ImageJ Updater special-cases
a couple of file types and skips e.g. the timestamps in .properties
files.

Since we would like the original Fiji Updater to update itself, at
least, and since it verifies the checksum of the downloaded file,
we need to make sure that the file Fiji_Updater.jar does not contain
such fiddly files.

MiniMaven: try to be gentle with invalid dependencies

Technically, it is an error when the version of a dependency is not
set. But let's try to just go on without it.

MiniMaven: make sure that .pom *and* .jar are downloaded

Tobias Pietzsch noticed that in certain circumstances, jdom's .jar
file was missing. While this developer is clueless as to the reason,
it is his conviction that we should deal with the situation nicely.

MiniMaven: avoid IllegalThreadStateException

We started the ReadInto threads twice when executing programs. Hence
the programs always failed to execute.

Updater: add some functions to access the ImageJ Updater

This is the first commit to finish the move of the Fiji Updater into
the code base of ImageJ2.

The idea: Fiji will transparently hand off to the ImageJ Updater as
included in ImageJ 2.0.0-beta3.

We will keep the Fiji Updater as this rudimentary ImageJ1 plugin
which knows only to run the ImageJ Updater, and how to load it from
the Update Site of ImageJ2 if it is not available locally yet.

Special-case the first ImageJ Updater run

We want to yse the ImageJ Updater which recently has been forked off of
the Fiji Updater with the idea to move the component to ImageJ2. But
that means that we want to access the ImageJ Updater from within Fiji
without having its sources anymore.

So the idea is to instantiate the Updater itself from a known-good
version on the ImageJ Update site and let it install the ImageJ
Updater. After that, we use the ImageJ Updater happily ever after.

Refactor the ImageJ Updater Adapter

Let's separate the part specific to ImageJ 1.x from the part that is
specific to accessing the ImageJ Updater (part of ImageJ2). This will
allow us to add back the command-line interfaces of the Fiji Updater
(which will ask ImageJ Updater to do the job, just like the Fiji
Updater GUI will).
