Notepad enhancements:
1. Added line ending handling, so that Notepad can handle line endings
other than CR/LF. This is specified in a dropdown menu similar to the
text encoding. Consequently, I've moved text handling to a new file,
text.c
2. Implemented the Find command
3. Changed some dialog titles to be 'Notepad' instead of 'ERROR', in
line with how Windows notepad works.
4. The edit control now has the style ES_NOHIDESEL specified
