Moving tool_dependencies.xml into a separate BLAST+ package
Introduce package_blast_plus_2_2_26 as dependency

Suggested by Nicola Soranzo, implemented with advice from
Bjoern Gruening. This closes issue #7, see also:
http://lists.bx.psu.edu/pipermail/galaxy-dev/2013-August/015890.html
Update README regarding package_blast_plus_2_2_26 dependency
add boost as explicit dependency
Use the IUC BOOST package
Download NCBI BLAST+ binaries (tested on 64 bit Linux)

Since this isn't possible via the Galaxy XML yet, does the
platform selection in shell script.
Replace tabs with spaces
Simpler to use *.rst for all the README files
Update citation information
Simpler to have blastxml_to_top_descr request latest blast_datatypes
Can use unicode for accents in the RST help text within tool XML
Fix typo (wrong filename) in README file
TravisCI integration for continous integration via Galaxy tool functional tests.

This works by installing a copy of Galaxy and the BLAST+ binaries,
doing a 'manual install' of the Galaxy Tools in this repository,
and then running the Galaxy tool functional test script.

The installation including the test suite setting up the database
(via the migration scripts) alone takes about 3m30s. This is not
ideal... but running the tests takes quite a bit longer :(

To minimise the test run time, we use a custom tool_conf.xml with
only our tools (and the data upload tool) to avoid wasting time
loading tools we will not be testing. Similarly we use a custom
datatypes_conf.xml with just the datatypes of interest to avoid
wasting time loading the other formats.

We are also using wget from a GitHub mirror of the Galaxy repository,
git clone of the mirror was a little slower, wget from the official
Galaxy bitbucket slower still, and an hg close slowest of all.
Mention testing in README file & TravisCI build image
