Update install.php5

Defaulting to MySQL here is really dumb. There is an explicit type as an argument so falling back to mysql could result in "I couldn't write to path ....db" despite the real error that the include of the sqlite3/code/SQLiteDatabaseConfigurationHelper.php failed for some reason.

Other uses of getDatabaseConfigurationHelper also need a similar error handler.

BUG Ensure TreeMultiSelectField doesn't populate menus with "unchanged".

which causes menus to not load and generates console errors. Fixes #2795
Add getters for Versioned object properties
BUG Default Member.Locale now chooses a better default value when i18n.locale is not a valid translation

This will resolve issues in cases where the site locale may be assigned a value that does not have an explicit translation. E.g. if the locale is en_NZ (and it's appropriate for this to be the assigned locale), Afrikaans will no longer be the default selected locale when creating members. Now en_US is chosen as a better fallback default.

This is a minor ease of use fix that means fewer CMS users can be accidentally created in Afrikaans within NZ based sites.

Test cases included.
