V2.0 update

## Features 

### Open
* Now returns the activeDocument after opening the file.

### JSLayer()
* Removed semicolon from output.

### Document
* Added FullName() which returns path to the .psd file.
* Changed Filename() to DumpFile(), as Filename was misleading.
* Dump function now saves the file as well,
to help reduce the frequency of de-syncs.
* Dump function now saves json files alongside the .psds
instead of in a separate data folder- encountered issues when using
the package as a module in go 1.11beta2.
* Added Save()

## Testing
* Added TestDocument_Save
* Added TestDocument_Dump

## Misc.
* Renamed pkgpath to pkgPath, to better fit go's standards.

## Fixes
* DoAction now runs correctly.
