Fix a few minor issues

Patch Set 1:

- Commit 493adfae47673523e5ecd10d1e3606dc85d2b0d8: Adjust some DCA evaluation keys to comply with the general settings
- Commit 2750d7b39b7c7fcb4f8e12f00b479f26511e38b5: Adjust the styling of the `syncShowUnchanged` checkbox input element
- Commit b2ef9602acd57744c728c91e5694d864a03444fd: Add a few missing `title` attributes for the file/page manager links. Unfortunately, the variables from `modules.php` (resp. `modules.xlf`) are not loaded at this point. Otherwise I would have taken e.g. the variables `$GLOBALS['TL_LANG']['MOD']['files'][1]` and `$GLOBALS['TL_LANG']['MOD']['page'][1]`as `title` value.
- Commit 70ed8e07b2f2f0513dbc4a5d594d2916d1e7cf79: Add some missing strings to `default.xlf` (details view)
