Add text wrapping for cells to the writer
Created originally on Bitbucket by Anonymous
Looking at style.py It appears that the code hsa the ability to create wrapped text fields (self.wrap_text = False), but when the value is set to True it is never written in the output XML.
The following addition in writer/styles.py (1.5.3) fixes the problem:
205a206,208 {{{ #!python if hash(st.alignment.wrap_text) != hash(style.DEFAULTS.alignment.wrap_text): alignments['wrapText'] = '1'
}}}
