Removed verbose explanation
Adding new hostname
Changed header
Docstring adjustment
Showing target/turnover as numbers instead of only as percentage
Better 'werkvoorraad' calculation: only counting external projects again
Fixed adding PL/PM automatically upon model creation.

Originally the project wasn't saved yet, so foreign keys couldn't be added to it.
PM/PL get their hourly tariff automatically set upon project creation
More useful week representation
Showing totals
Calculating the money amount that is bookable per person, in addition to the
already-calculated amount of available external hours per person.
Showing still-to-turn-over amounts and totals
Added 'startup meeting done' boolean on project
Using new meaning of 'is_accepted' in the templates
Allowing PM/PL to edit a project (but with fewer fields)
Added financial remark field on project.

This one is only editable by office management, the regular remark field is also
editable by PL/PM.
End date not editable after project is accepted
Showing startup meeting icon
Comment fix
A PL cannot edit hours anymore once the startup meeting has been done.
