Autocompletion for role button in relation dialog

[stoecker]

The role field in relation dialog should support autocomplete and the drop-down-box (prefilled with the roles from presets, which are currently not parsed).

Also the dialog should remember the last selection of closing the session. Usually the chance is high that one handles equal roles one after another (e.g. for multipolygons, routes, ...)

@bastiK: Can you do this? You did a lot of autocomplete changes lately.

[stoecker]

The autocmplete code is already there, don't know why it did not work.

See r3289 and [o21539] for parsing of preset role definitions and remembering value.

Remaining issue, the role field should be a autocompletion combobox instead of the text field it is now.

[bastiK]

I think you need at least one applied role of that type in the current data set. There should be "silent" presets for this (and also some other common tags that are not in the presets).

[bastiK]

Further enhancement:

Have higher priority for roles that fit the type of the relation. E.g. type=multipolygon -> role: outer,inner is suggested.

[stoecker]

What do you mean with previous comment? The role presets have been added in my latest change. Currently not yet type dependent. It didn't want to change the autocomplete interface too much before I really understand it (it changed really a lot :-).

Role handling could be now be done like for tags. The RoleChecker in validator already has code how to find matching preset(s) for a given relation. This can be used to choose set of "wanted" roles.

Common tags not in the presets should be added in presets instead of doing workarounds.

[bastiK]

OK, the roles should be parsed from the presets.

Common tags not in the presets should be added in presets instead of doing workarounds.

What about these: fixme, fixme=incomplete, note, loc_name, alt_name, de:amtlicher_gemeindeschluessel and TMC related stuff.

I think auto completion is working nicely (besides suggesting forward when I in fact want forward_stop). Anything to be done?

Take the object's type into account could solve some of these cases where roles with similar names exist.
