wxGUI/locdownload: show progress of downloading new location as Data Catalog info bar message

[tmszi]

Implementing/close feature #3278.

Works nicely, thanks for improvement. @tmszi Some notes below:

* would be nice to avoid blinking `Abort` button when progress is updated (minor issue)

* when download process is finished `Abort` button does nothing - it should be automatically removed (major issue)

Thank for review and suggestions. Both issues are fixed with commit no. https://github.com/OSGeo/grass/pull/3287/commits/cfb83a5ef94ef39baf3bcb22f2b9f34f02b574dd.

Thank for review and suggestions. Both issues are fixed with commit no.

Great, I tested updated PR and I can confirm that both issues are fixed.

@tmszi Small note: It make sense to me to show the dialog for selecting location to be downloaded when process of downloading is aborted. I am just not sure whether it make sense to show the dialog on successful download.

When testing multiple times I am getting error:

I wasn't successfull to reproduce it.

I wasn't successfull to reproduce it.

I tested again with the same result:

@tmszi It seems to be related to multiple GRASS data dirs (databases). I tried to removed second data dir and download was successful then

I was not able to reproduce this bug in the main branch. So it seems to be related to this PR.

I can' reproduce it (I tried with 2 and 3 GRASS GIS database directories added). Could you send me exact follow steps to reproduce it, please?

Tested with Python/wxPython version:

GRASS fire_grass6data/demomapset:~ > python3 -c "import sys, wx; print(sys.version); print(wx.version())"
