Removed some dependencies

[miguelmaso]

Some should not belong to the HyperFEM core:

• DrWatson: This package is very useful for managing simulations and should be in a global project where the simulations are defined (replaced by UnPack)
• Profile: This package should belong to a testing/profiling project/subproject
• ProfileView: This package should belong to a testing/profiling project/subproject
• TimerOutputs: This package should belong to a testing/profiling project/subproject (already present in test/)

Added:

• UnPack: this lightweight package provides the @unpack macro.
