fix(android): null value incorrectly interpreted as boolean

[garymathews]

• Include changes from fix(android): automatically migrate to new cipher #40
• Update sqlcipher to version 4.2.0
• Use AbstractWindowedCursor like Titanium.Database
• Build using Titanium SDK 8.X.X

TEST CASE

const encLib = require('appcelerator.encrypteddatabase');
const db = Ti.Database.open('mydb');
const encDB = encLib.open('myencdb');

[db, encDB].forEach(x => {
	x.execute('CREATE TEMPORARY TABLE IF NOT EXISTS test(col TEXT)');
	x.execute('INSERT INTO test VALUES (NULL)');
	const rs = x.execute('SELECT col FROM test');
	while (rs.isValidRow()) {
        const fbn = rs.fieldByName('col');
        const f = rs.field(0);
		console.warn('col fieldByName: ' + JSON.stringify(fbn) + ' (' + typeof fbn + ')');
		console.warn('col field: ' + JSON.stringify(f) + ' (' + typeof f + ')');
		rs.next();
	}
	rs.close();
	x.close();
});

[WARN]  col fieldByName: null (object)
[WARN]  col field: null (object)
[WARN]  col fieldByName: null (object)
[WARN]  col field: null (object)
