Rename landing page & add taglines to be more SEO-optimized

Home | KA Lite isn't at all optimized for Google Rankings. Current title for the develop branch is "KA Lite: an offline, installable version of Khan Academy", which is much better than Home | KA Lite, but could possibly use work. We could also afford to add more SEO-friendly taglines that utilize high-hit terms like "online education" "educational software" and "free online courses".

One of our largest problems with SEO is that even though we specialize in "offline education", this term is rarely searched (~20 hits). However, "online education" is ranked very highly (110,000 hits).

@bcipolli thought up a few taglines that might account for this, listed below:

Bringing online education offline
Bringing online education to offline communities (especially partial to this one)
Online education, zero bandwidth

I added the second one to the "About" page following the "KA Lite" header.

Possible titles for the landing page also include:

Free courses in math, science, and more | KA Lite
Free educational software | KA Lite
KA Lite: an installable, offline version of Khan Academy (basically what we have now)
Free courses utilizing Khan Academy's Online Educational Software | KA Lite (way too wordy but also SEO-dense)

It's significant to note that "Khan Academy" gets 2.24M hits and most likely isn't utilized very much by competitors on AdWords - we could probably get ads on the first page of this search for cheap.

Looking for some feedback about a possible title change, as well as the tagline I added (this could potentially go anywhere, and I would find it better if it were in anchor text for SEO purposes).
