Improve comments in some syntax definitions (Part 2)
This is the continuation of !29 (merged)
Add ##Alerts and ##Modelines in all comments and add/fix the <comment .../>
elements of the <comments>
group.
For example, in the comment elements:
- Add the region attribute in comment of type multiLine if it's missing. Folding in multiline comment is also added if missing.
- Add the position attribute in comment of type singleLine in indentation-sensitive languages.
- Remove duplicate comment elements, as only one type singleLine and multiLine are supported.
Also, in MAB-DB (mab.xml) and nesC (nesc.xml) some RegEx rules are substituted for optimization and in Mustache/Handlebars (mustache.xml) the Handlebars comments are used in the <comment .../>
elements. In nesC a hard color (itemData Function) is removed.
