Multithreading support

Support for multithreading included in this release (allows for faster downloads at large quantities of downloads due to extra worker threads).

Please bear in mind I am still a beginner at both web scraping and multithreading so all suggestions are welcome

Full Changelog: v0.1.0...v0.1.1

minor fixes

Just some minor changes to avoid infinite loops while searching because I didn't notice this until some manual testing.

Preliminary release

Just a preliminary release for a Google image web scraper written in Python, basic code only, as this is a learning experience for me more than a production grade project.
