Added a new elisp module "javaimport.el", aiming at reinforce the capabilities
to import a class form any source file within the current project file tree, any
library (JAR) used in the current project, or from standard JDK/GDK APIs.

As a first step, in this commit I added the function to scan all the classes
defined with a given source file.

 #ISSUE: if the word "class" is used in comments, it is wrongly used as a class
declarator and the word after is used as the class name!
=> Suppressing all comments within the temporary buffer before scanning classes
would correct the problem.
Issue resolved in javaimport.el (see last commit).
Removing all comments (AND string litterals!) allowing resolving
the issue.
javaimport.el: I made the returned class list include the access modifier
set on each class.

Before:
(class1 class2 ... classN)

After:
((class1 access-mod1) (class2 access-mod2) ... (classN access-modN))
