[PATCH] Add \endifrsthead to longtable export

[PATCH] Add \endifrsthead to longtable export

Aloha all,

Previously, export of LaTeX longtables that spanned a page break
generated a caption on each page, resulting in multiple entries in the
table of contents.

The attached patch for ox-latex.el implements the \endfirsthead command
so the caption only appears once, at the top of the table. Subsequent
pages of the table start with "Continued from previous page".

All the best,
Tom
