Show a warning about partial download when changing the install folder

[arielj]

Problem description

Heroic progressively downloads the game in the selected folder. When an installation is stopped, the user can select to keep the files there to continue the download at another time. If the user changes the installation folder in the new installation dialog, Heroic removes the % of already downloaded files from the dialog (which is correct) but the user may never notice the previous partial download will still use disk space and then there's no way to remove that from within Heroic, the user has to manually download that folder.

Feature description

When there's previous data from a partial stopped download, show an alert to the user if they try to change the installation folder so they know that will:

• reset the partially downloaded % to 0
• leave the old files in the old folder

Alternatives

Other things we could try:

• try to move the partial downloads first to the new folder before resuming the download, so the % is not lost (may be complicated if too many GB)
• give the user the option to remove the old files if they confirm the installation in a new directory
• prevent the user changing the install folder unless they confirm they are aware of that (maybe too drastic)
• suggest the user to complete the installation and to then use the move feature to move the game to the desired new location
