Map contributors to use canonical real names and email addresses

[sbesson]

These updates reviews all commits and associates a canonical real name and email address to each individual contributor. The following rules are used for the construction of the .mailmap file:

• for all contributors who were also employees of the University of Dundee of Glencoe Software, the @dundee.ac.uk or @glencoesoftware.com email address is used as the canonical email address
• for all contributors with an executed CLA, the email address sent via the CLA is used as the canonical address
• for all contributors, the name used in https://www.openmicroscopy.org/teams/ or https://www.openmicroscopy.org/contributors/ is used as the canonical real name.

The .mailmap is constructed according to the official documentation using one of the two forms:

Proper Name <proper@email.xx> <commit@email.xx>

for mapping different email addresses and

Proper Name <proper@email.xx> Commit Name <commit@email.xx>

for mapping different real names.

The unique list of commit authors can be generated and reviewing using git shortlog -se
