[ptx] .jpe suffix patch fix

[Stanislav Brabec]

My intention of the patch is simple - I only want to create panoramas
with unchanged and not renamed images from my camera (and other camera
models). All other programs in my computer I use daily know about .jpe -
Shared MIME Info (and whole GNOME) knows about .jpe, GIMP knows
about .jpe. Only Hugin/nona does not. Standard says nothing about JFIF
file name suffix and all three forms JPG, JPEG, JPE are common.

If I understand correctly the JPE rationale, it is probably a Windows
trick - Windows associate .JPG with image viewer. But Photoshop
assiciates .JPE, too. It means, that .JPE files are opened by Photoshop
as default. 

Shared MIME Info:
  <mime-type type="image/jpeg">
    <comment>JPEG image</comment>
    <magic priority="50">
      <match value="\377\330\377" type="string" offset="0"/>
      <match value="0xffd8" type="big16" offset="0"/>
    </magic>
    <glob pattern="*.jpeg"/>
    <glob pattern="*.jpg"/>
    <glob pattern="*.jpe"/>
  </mime-type>

GIMP:
  gimp_register_magic_load_handler ("file_jpeg_load",
                                    "jpg,jpeg,jpe",
                                    "",
                                    "6,string,JFIF,6,string,Exif");
