#50 PDF and RTF export and words broken by linebreaks

[Domhnall101]

ON HOLD UNTILL We have a conversation on the scholarly requirements for export then to implement them consistently across the export options

Line breaks where there is a split word - joining when turned onto continuous text.
Settings to enable this to be in the control of the user.

[Patrick]

To note: The current interface for XML,RTF, or PDF export do not have an option to rejoin broken words at all.

Commented out are the following parameters which can be exposed when supported by the exporter and relevant:

1. notes:sideBySide - Split page vertically and line notes up with lines of transcription
2. notes:footNote - Show notes with reference on each page
3. linebreak:pageonly - Break at page, but not at lines
4. exportWordbreak:STRING - String for wordbreaking to rejoin split words
5. exportLinebreakString:STRING - String (likely a <tag>) to add at the end of each line in XML-type export
6. useLinebreakingString:BOOL - Boolean for whether above string in included

Uncommenting any of these label/input pairs will put the option on screen and send the parameter with the form.
