Merge branch 'THchangesOct2015' of https://git.embl.de/dinkel/linuxcommandline into THchangesOct2015

Merging changes to PDF since last pull.

Made a few corrections to language in the main body of text. Changed the man example to man echo instead of man man. Added a bit about tab autocompletion into the introduction. Rewrote and shortened the section on the Bio-IT Project. Removed mention of CMCI from the Centres section. Added some comments to Comments.txt.

Conflicts:
	general/CertificateOfParticipation.tex

Use pure LaTeX to batch create Certificates. Just add names into file CertificateOfParticipation_names.csv
