Code Completion updated

In Scala source files, code completion returns the valid Scala and Java proposals.

Completion overwrites new

Users can choose if identifiers inserted by the code completion mechanism should overwrite already existing ones. This is a very useful feauture if one decides to change already existing source code. For example, if we have the following

List(1).fl^map(List(_))

where ^ denotes the cursors position, it would not be that useful when as completion flatMap is chosen but the already existing map is not replaced. Completion overwrites allow exactly these sort of replacements. They need to be configured in Preferences Java Editor Content Assist and then in the section Insertion.

A small detail do mention here, is, that it is possible to toggle between the completion modes by holding Ctrl while applying the completion.
