Added complete license text

**Fixes #47 **
In this pull request I added License text of all the licenses available at https://spdx.org/licenses/
Also I sorted list of License in alphabetical order.
-> New License Description page

-> Old License Description page

Thanks.
But this list also includes deprecated licenses. Before including them, it would be better to have conclusion on how extra information on licenses will be handled -- which is is kind of what #39 is all about.

Also I'm not sure a huge .csv file is the correct way to have all the data...

Okay,

• For now let me remove deprecated licenses.
• @zvr I don't think large .csv file will create any issue. (infact populate_db.py takes less than 1 minute to populate database after this fix commit the changes to DB only once it's populated #43 (thanks to you))
• Advantage of using .csv file is that anyone can populate database without internet connectivity. (there are other options to populate database but they will require internet connectivity)
• Once there has to be way to use a newer version of the license list #39 is solved, data handling will be much better but this csv file will be needed to initially populate database with license text info. So, this pull request needs to be get merged.

@zvr please review this PR and if there is any issue (besides csv size) is left, please let me know. The csv file is created from https://github.com/spdx/license-list-data and contains complete data.

Link to my script to generate csv (with lic. text).
Clone https://github.com/spdx/license-list-data and in same directory run myscript

[shivanshuraj1333]

If it was created, we need the software that created it, for review. But we shouldn't be transforming the data in other formats...

@zvr please review this. I wrote another script which will use upstream data directly to populate database solving #52.
Note: Both (this and new script) uses original data extracted from https://github.com/spdx/license-list-data

I have made comments about the update script in #53; same apply here.

Updated .csv file from latest license release by SPDX. This is the link to my gist for generating csv file for every new release of licenses by SDPX.
