Docs for showOpenDialog and showSaveDialog

[SheetJSDev]

First off, awesome work! We put together a small example of SheetJS + NeutralinoJS to read and write spreadsheet files.

There were a few minor nits in the documentation around showOpenDialog and showSaveDialog:

showOpenDialog

1) Options:

filter Filter[] ...

The actual code example uses filters.

2) Current code block:

let entries = await Neutralino.os.showOpenDialog('Save your diagram', {

The title probably should be "Open a diagram"

showSaveDialog

1) Current description:

Shows the file open dialog.

The description should be "Shows the file save dialog."

2) Options:

filter Filter[] ...

That probably should be filters

3) Current code block:

let entry = await Neutralino.os.showSaveDialog('Open a file', {

The title probably should be "Save to file"
