qmljs: handle js directives .pragma and .import

The directives .pragma and .import are not included in the AST.
Their source code locations are not stored in any other place.
As a result, when reformatting the source, they simply disappear.

This patch keep track of their source code locations, so they are
not removed when reformatting the source code.
This patch contains also some modification in the lexer that should
probably be ported to the qtdeclarative version.
