Uncomplete instruction about Ghisler's SFTP-plugin 1.4.1

[Jivan_Mukta]

The correct instruction in readme.txt have to be

Installation instructions:
==========================
This plugin needs the dlls libeay32.dll, libssh2.dll and zlib1.dll...

I also suggest to Mr. Ghishler the main motivation of
his SFTP software development presents in a few words in readme.txt before the instructions.

Why we need another Sequre FTP-plugin?

"1/ The development of the old SFTP plugin (http://...) is not going to continue.
2/ 64-bit support
3/ ..."

something like this, wchich will be clear for ordinary TC SFTP user.
Not too much specific advantages. So this few words also to become a better notation about this new SFTP-plugin in web pages.

More specific advantages could be a part of other section.

Thank you for attention!
