Force!

Added Jasmine tests for the static part of the library. The dynamic part was thorougly tested already, but I hope to add soon some tests for that as well.

types.js included in strings.js is updated to the latest version now.

Many little enhancements and a few minor bug fixes.

Added:

• Strings.get().

Removed:

• Strings.force, as force is now implemented in types.js. Use Strings.forceString, or the other useful force'Types' from types.js.
