Format for 0 before decimal

This is a fauture request of a format setting which would control if you want to format numbers under 1 and over 0 without the 0 before the decimal place.

Example code not formatted:
```Lua
local firstNum = 1.8
local secondNum = 0.2
```
Formatted:
```Lua
local firstNum = 1.8
local secondNum = .2
```

Thanks! :D Love this extension!
