Provide a snap package for Linux about symphytum HOT 4 CLOSED

Stuck at the moment on #50 because of the following error on launch:

../symphytum-snap/snap$ symphytum 
snap libpthread.so.0: symbol __mmap, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference [...]

relocation error: /snap/symphytum/1/lib/x86_64-linux-gnu/libdl.so.2: symbol _dl_catch_error, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference[...]

This happens because one is supposed to build snaps on Ubuntu 16.04, but since the shipped Qt version is too old (no HiDPI call which is used in main.cpp). It needs at least Qt 5.6.

So I will pause this until 18.04 LTS is released.
Or is there another way?

Looks like using a development version of snapcraft (from snap store itself) helps, maybe they fixed the bug.

sudo apt autoremove snapcraft
sudo snap install --edge snapcraft

Now stuck with python due to same issue. OK waiting for 18.04 it is then...

A basic snap package, including python dropbox sdk, for 16.04 works so far with latest work in #50.

Unresolved issues:

• HiDPI disabled until 18.04 ships which has updated Qt libs for packaging, since it works only on 16.04
• Snap fails to open links which use QDesktopServices::openurl(), oddly enough 16.04 opens browser links but same doesn't work on 17.10+ or on other distros like Arch. I guess this will be solved when snapd implements the xdg-open thing and other snapcraft updates.

After many hours of trying to make snaps work, I have to say this is stil way too immature, and so far the integration also sucks (mouse cursor, theming, file dialogs, .etc..). Snapcraft is supposed to make distribution for devs easier, but quite the contrary at this point.

Going to merge the basic snap support while waiting for a better state before shipping it.
