tiled has new releases

[prjemian]

Keeping an eye on the tiled releases, note that there are several (at least 5) new releases in the last week.

At least one of them requires a minimum server and client pair that are newer than we use now. Might cause us to change our code, either on the server side or the client side.

Started a tiled server (0.1.0a104) in a conda environment with newer tiled version (0.1.0a104). Then started this client. This exception was reported as status:

Error for server_uri='http://192.168.144.94:8000': 400: Python Tiled client reports version 0.1.0a96. Version 0.1.0a104 or higher is needed to communicate with this Tiled server. http://192.168.144.94:8000/api/v1/

@jilavsky, @canismarko : At some point, I must upgrade the tiled server on otz for this change (both client and server have a new minimum version, stated above). If you run your own tiled server, then you may not see this problem. But if you upgrade your tiled server, your Python clients will need the new version. Non-Python users might some changes in the API, I'm not sure about that.

Maybe the new version has Python client structure changes as well. This exception was raised (and the app crashed out) when double-clicking on a run in the QTableView:

Wait for #128 before working on this issue.

[prjemian]

I will create the new version of the server on a different port. Possibly 8020 (if it is not already taken), so http://otz.xray.aps.anl.gov:8020. We can test with either version, then.

[prjemian]

If the current version of gemviz tries to access an older tiled server, this exception may be raised when trying to connect:

Can this be recognized and translated into a more useful message? Such as: tiled server not compatible with this application. Can the client identify what version the tiled server is using?

[prjemian]

Don't bother translating this message. It is dependent on an old tiled version. Since tiled is in alpha development, do not write code to explain such transients. The interface may change further at this stage.

Note this important BUG report:

• https://github.com/bluesky/tiled/issues/566

Since we have various files which follow this naming pattern:

something.txt, something.md, and something.dat

we'll need this BUG resolved for general use.
