### Problem description
Currently, the providers use the method `isSavable()` to determine both
if they can use "Save" or "Save as".
This behaviour is problematic because some providers may need to be
saveable but not saveable as: for example the view provider. The
original provider may not allow to be saved.
### Implementation description
I separate these two behaviour by creating another function:
`isDumpable()`, that return true by default but can be overridden by the
provider to return false, if the provider should not be dumped in any
way.
### Additional things
While I was at it, I also marked "export" operations as needing the
"dumpable" flag. That way, we can't accidentally export the whole
address space of a process as base64.
I also added documentation for these some functions in Provider
This PR adds some documentation. It's actually pretty random, I followed
the function calls I was curious about and commented whenever I wasn't
sure/I thought it needed clarification
You might want to make sure to squash them, because the commits are kind
of a mess, I didn't went through the effort of interactive rebase
PR title is self explaining
I may modify other providers implementations to display a detailed error
message later
I'm not sure how to deal with other locales because the format changed.
Before, I had to add and comment the key in all locale files, now I'm
not so sure.
