Update version number
Remove trailing whitespace
Remove anon log warning
Remove unused import
Fix #21 (undo bug)

The fix for this bug removed the wildcard feature of spelling correction. I didn't like it anyway.
Avoid exception with hackish conditional
Move message modification functions to separate class

This unclutters the main class and allows unit testing of spelling correction.
Fix bug in capitalise function
Add tests for message modifiers

Tests for spelling correction are disabled as I don't know how to work with stubs.
Update for v1.8.2/v1.8.3
