More minor tune-ups
Fixing bug from my refactoring
Making Tortoise sliders return numbers
Fix speed slider so that models can go one tick at a time.
Fix widget queries and netlogo-display attribute
Only create view if it doesn't already exist
Small changes for code review
Fix js defaults for commands and reporters
Prevent the creation of view layers if they already exist.

Allos "save as html" to actually work.
Make sliders out of both range and number inputs.

Label marks the number input. Also, this consequently supports people
binding together an arbitrary number of widgets for custom sliders.
Delete unused code
Make speed slider always default to middle
Make monitors default to "N/A" when code throws runtime error

This is desktop NetLogo's behavior. See Virus for example
