Continuation of changes for #8

The char dictionary now contains some real examples and has been added to
the manifest so it can be loaded.
Completed support for multiple chars per emoji

This commit fixes #8 and starts to encode the SoftBank encoding required
for #9.
The options page has been completely removed as it no longer seems
necessary due to increased performance.
Fixed issue with line endings in char dictionary

Some lines in the character dictionary had incorrect new line characters.
All lines now use the same line ending.
