force recalculation in OpenOffice.

b62653f382 Add image buffers without a temporary file 
Use fmemopen to create an in-memory FILE for reading in image
attributes. This avoids creating a separate temporary file for every
image added to the worksheet.

Passing NULL as the first argument creates a buffer managed by fmemopen.
According to the system documentation, fclose will free the buffer, so
no further changes are needed.

fmemopen is defined by POSIX.1-2008, and on some platforms requires
_POSIX_C_SOURCE set to 200809L or greater. This is conditionally set in
the file (src/worksheet.c) where fmemopen is used.

This change includes a new USE_FMEMOPEN option for both CMake and make,
following the tradition set by USE_STANDARD_TMPFILE etc. This new option
is enabled on Travis.

See #287 #288

a0e6a362ba Removed LXW_ERROR_SHEETNAME_RESERVED warning. 
Removed LXW_ERROR_SHEETNAME_RESERVED warning which was used with
the reserved worksheet name "History". However, this is an
allowed worksheet name in some Excel variants so the warning has
been turned into a documentation note instead.

31a76c613a Use PREFIX for install_name 
Not DESTDIR because that's just the staging directory; the final location
will be at PREFIX.

Succeeds #209

4daf725bae Use DESTDIR and PREFIX instead of INSTALL_LOCATION 
PREFIX is the final location on the user's system. DESTDIR could
be staging directory for a package build, a chroot, etc. The
distinction is important because you don't want DESTDIR to end up
in paths compiled into the program, e.g. the location of a helpfile
or library.

(Applies only to the makefiles, not CMake)

Resolves #216
