Symbolic signal/property references

[josephbirkner]

Changes acc. to #86:

• §1 Signal can be constructed in with Module ... clause, module scope will be set automatically. Signal may be used as parameter signal=my_signal in state declaration
• §2 Referring to signals by name should become illegal. The s(...) function will be removed. Refer either by exported module variable, or by the respective Property/State APIs.
• §3 Setting Signal constraint properties like min_age, max_age, detached, will be moved from constructor parameters to chainable function calls: my_signal.min_age(30).detached(). Each function call returns a copy of the signal with the respective member value change.
• §4 Properties will be referrable by symbols. The context's push/pop/setitem/getitem functions will be changed accordingly.
• §5 It should be prevented, that developers call a property's read/write function directly. For this purpose, context should always adopt copies of the respective property objects. The originals will be untouched. An exception to this rule is generally made for child properties, since they mark an advanced use-case where properties are generally created dynamically, and usually accessed through their path anyway.
• §6 The PropertyBase class will be renamed to Property.
