Switched out a lot of the reflection extension names

1) Switched out a lot of the reflection names, dropped get and set from
them (ex: getproperty/setproperty is just property).
2) CallMethod is now just Call.
3) CreateInstance became Create and added versions that accept
IEnumerable<Type> and will create one of each of the types specified).
4) A number of reflection oriented extensions that exported info for the
assembly, type, etc. were renamed to ToString.
5) IsOfType is now just Is.
6) IsIEnumerable has been removed.
