* syntax_tests: allow to "bless" tests, and don't use a regexp
A regexp was used at the beginning because I thought we would want to
allow error to contains things that were not predictable or that would
often change. But this is not the case¹. It is better to actually test
for the full error message
¹ well actually it was the case for path, but there is another substitution to
`📂` for the manifest directory
* syntax_tests: Bless the tests
* syntax_tests: Manual adjust after bless
Because there used to be comments on the same line of the message which
bless don't support
* Fix error message with path on windows
- The debug implementation of path make double slash, that's not what
we want to show the user
- normalize paths to use `/` so the test passes
Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
If the last position expression is invalid due to an unrelated error,
the code that tries to do the interpolation was panicking with the
message "The last should never be invalid". (Because it assumed that
invalid meant that it was not set, and we added a 100% for that last
one if it wasn't set. But if it is set and invalid, this would error.)
