fix doap
Merge remote-tracking branch 'paolo/master'
Start a msiextract tool
wixl: fix application name
build: lower gio and libxml2 requirements for wixl

These versions are present in RHEL6.  However, there is still
an undefined reference to g_hash_table_add.
wixl: do not use g_hash_table_add

This is not supported in GLib 2.22, which is the version used in RHEL6.
build: libuuid dependency is now mandatory

This was just a hack because Fedora mingw does not have a libuuid
port.  It can go.  And we can also always build wixl.
build: add dist-xz
msibuild: add missing include file
wixl: add --wxidir option
