Block loading/saving campaign from/to installation dir

Partially addresses #4209

Description of the Change

This change will stop users from saving campaign files into the installation directory.
If the user tries to do so a dialog will appear telling them that they are unable to do so and after clicking Ok they will be returned to the save dialog where they can choose another location.

As well as this if the user attempts to load a campaign file from the installation directory a dialog will appear informing them its not supported and asking them to copy the file elsewhere and try again. In this case they will not be returned to the load dialog.

Possible Drawbacks

I was not able to address the other requirements like default install to use version number as all attempts I tried just broke the msi builder.

Release Notes

• MapTool will now block users from saving or loading campaigns from the installation directory.

When I put myself in the shoes of a user that have fallen into this trap, I see two problems on the loading side (saving side seem fine to me):

1. Not all users may readily know where there installation directory is, and no direction given to them on how to find it.
2. Even if a user does know where it is, it's a lot of traversal require to remedy the situation. First navigating to the install directory in the file explorer, then navigating somewhere else to put the file, then going back to MapTool and navigating again to the new location via the Load Campaign dialog.

We can help the user out a bit more by:

1. Changing the message to read something like: "MapTool does not support loading the campaign from the installation directory. Please select a new location for the file."
2. When they close the message, we immediately open a save dialog and let them pick the new location right there.

I do like forcing them to Save As immediately.

However, if they Cancel out of that dialog (or just close it), the File > Save option should be disabled, forcing them to use File > Save As... and picking a new location.

Changed it so file is still loaded but user gets this message

This occurs from both load and recent campaigns

Then when trying to save

I decided against opening the save dialog right away as some is going to just click ok on the dialog when its first presented and ben prompted with a save dialog and be confused.

Does this extend to when people try to save other MT assets to the install directory like tokens, tables, campaign props, macro sets, etc?

The updated change blocks Campaign, Tokens, Tables, Props, Macros, Maps from being saved into the install directory. It does not yet stop screenshots (they are handled differently. so I will get to them in a later change, they are also less likely to be a problem.)
