Umlauter: automatically add Umlauts par Florian

Try typing something like "Kuehe" in a textbox followed by a space or period to see it corrected! Useful when typing German on US-keyboards.

On computer systems that don't support them, German words like "Erklärung" are often written as "Erklaerung" to avoid the use of diacritic letters. Though this is readable, it looks odd. An easy solution would be to replace all two letter combinations to their proper Umlaut-form and though this fixes 100% of potential words, there are too many false positives (for example the word "neue" would never be written "neü"). This project uses machine learning to predict if a substitution should be made.
