New Pretty printing feature

[linuxras]

Hi Nicholas,

First I would like to say thanks for making this program it was almost perfect for my needs.

I have however added a couple of features so it can do pretty prinnting
{
"var":"value",
"var2":"value2",
"vararray": [
'val1',
...
]
}
vs
{ "var":"value", "var2":"value2", "vararray": [ 'val1','etc...']}

The second is to be able to disable the unicode escaping of HTML entities such as <>

I have marked this version 0.1.1

Please accept these changes.

Thanks!!!
