Update to Settings handling

Two simple changes here
1) Reordered the settings in GlobalVariables for better flow. Changed default to display in browser only to make it easy for first run - only vCenter server address needed to run by default.

2) Fixed spacing on settings write after config (or import). Previously some settings were getting written back incorrectly.
Example:
Original variable line
```
$variable = "value"
$variable = value
```
Rewritten after config (or import)
```
$variable =" value"
$variable =value
```

Now will rewrite properly after config (or import)
```
$variable = "value"
$variable = value
```
