Support for bookmarkable URL for reports.

[mysticfall]

Add support for the bookmarkable URLs for each reports. And we can add someway to provide EL context variables for additional request parameters as well (see #37)

[mysticfall]

With this change, you can now open an existing report using an URL like this:

• http://localhost:8080/pivot4j/open.xhtml?path=_[path to the report]_

In case of the Pentaho plugin, for example :

• http://localhost:8080/pentaho/plugin/pivot4j/faces/open.xhtml?**path=/home/admin/test.pivot4j**

(Pentaho URL starts with lower case '/home', not '/Home'. And if you know the ID of the file, you can also use fileId parameter with it, instead of the path parameter)

Combined with #37, you can pass additional parameters to the URL and refer them in your MDX using the FreeMarker expression language.

For example, with MDX like below,

SELECT {[Measures].[Store Cost], [Measures].[Unit Sales]} ON COLUMNS, 
Hierarchize({[Product].[All Products], [Product].[Drink], [Product].[Food], [Product].[Non-Consumable]}) ON ROWS 
FROM [Sales] WHERE $['[Gender]].[' + (parameters.gender!'All Gender') + ']]']

you can pass the gender parameter like this:

• http://localhost:8080/pivot4j/open.xhtml?path=/aaa&**gender=F**

Note that, expressions used in WITH MEMBER or WHERE clauses are 'sticky', which means they are preserved even if the MDX is transformed by drill down, sorting, etc. In this way, you can save the modified MDX with your report and still use a parameterized URL to open it next time.

What if we have to pass multiple parameters? For example if I have to filter with age 25 and 26 or age range 25 to 30, how can I do that?

[mysticfall]

@ravindragullapalli You can just define the parameter multiple times with different values (i.e. ?age=25&age=26) and expect the parameter value to be java.util.List.

Sorry for the very late response.
