Does not handle APKs with spaces in the name properly

Calling APKTool with following command
b'java -Djava.awt.headless=true -jar c:\\\\program files\\\\python36\\\\lib\\\\site-packages\\\\qark-3.0.0-py3.6.egg\\\\qark\\\\decompiler\\\\..\\\\lib\\\\apktool/apktool.jar d D:\\\\mas\\\\NPTU.apk --no-src --force -m --output D:\\\\mas\\\\build\\\\qark\\\\apktool'

Error: Unable to access jarfile c:\program

It seems that APKTool take
`c:\\\\program files\\\\python36\\\\lib\\\\site-packages\\\\qark-3.0.0-py3.6.egg\\\\qark\\\\decompiler\\\\..\\\\lib\\\\apktool/apktool.jar`
as 2 arguments, since there is a `space` in the "program files"
This will also cause the failure of `move manifest into proper location`, because there is no manifest to move

so I change the decompiler.py at line 29
`APK_TOOL_COMMAND = ("java -Djava.awt.headless=true -jar {apktool_path}/apktool.jar "
"d {path_to_source} --no-src --force -m --output {build_directory}")`
to
`APK_TOOL_COMMAND = ("java -Djava.awt.headless=true -jar '{apktool_path}/apktool.jar' "
"d '{path_to_source}' --no-src --force -m --output '{build_directory}'")`

I just simply add quotes in every path-argument and fix it

Maybe we should add quotes in every command not just APKTool in case there is more `space` in users' path

Start with decompiler.py around line 29, where APK_TOOL_COMMAND is assembled, and reproduce the command using an APK or installation path containing spaces. Verify that the APKTool invocation and subsequent manifest handling succeed when paths contain spaces; no specific test file is mentioned in the issue.
