Update README & .classpath.
Swapped the ordering of searching for bold/underline/invert vs. colours so that ^B^B (or similar) can be used to separate a colour code from a number that should be coloured (for those of us - like me until five minutes ago - who hadn't thought of zero-padding single-digit colour codes). This brings QuasselDroid's behaviour in line with the official Quassel client.
