Size reduction

Reduced the size of assets to drastically reduce the size of the APK. No functionality changes.

First Android release version

Contains first versions of the home page, construct information pages (and index pages for them), and about page. Also contains first version of the Magic Words feature in the construct information pages where 'Magic Words' can be searched in the text.

Size is really large at the moment because of assets. Will be optimized in later releases.
