Getting types wrong on new exercises

[renlok]

Only the first set of a new exercise should set its type all none unit sets should then default to that

[renlok]

line 428 block add a $this->exercises[$i]['update'] flag that setExerciseDefaultTypes checks + in the block have new set to false (done want to continually update it)

[renlok]

The ordering of types weight should be first so unless a unit is used all new exercises are assumed to be weight based

Needs more testing maybe fixed in 00113a5

pretty sure this is fixed now, can close
