* Update README.txt
As of Ubuntu 16.10, libpng12-dev is replaced with libpng12-0, since libpng12-0 is available in 16.04 repositories, I think that needed to be changed.
Also I changed 'git-core' to 'git' for fedora users, keep it consistent with the ubuntu/debian instructions.
* Update README.txt
The package docs for the git-core Ubuntu package in all supported
Ubuntu versions, including 12.04 say:
This is a transitional dummy package. The 'git-core' package has been
renamed to 'git', which has been installed automatically. This git-core
package is now obsolete, and can safely be removed from the system if no
other package depends on it.
Fixes#4109
On Debian 8...
```
Package libjpeg8-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libjpeg62-turbo-dev
```
Using libjpeg-dev should make the OS select the most appropriate lib to be installed.
These are the packages available on Debian 8.
```
libjpeg-dev - Development files for the JPEG library [dummy package]
libjpeg-turbo-progs - Programs for manipulating JPEG files
libjpeg-turbo-progs-dbg - Programs for manipulating JPEG files (debugging symbols)
libjpeg62-turbo - libjpeg-turbo JPEG runtime library
libjpeg62-turbo-dbg - Debugging symbols for the libjpeg-turbo JPEG library
libjpeg62-turbo-dev - Development files for the libjpeg-turbo JPEG library
libturbojpeg1 - TurboJPEG runtime library - SIMD optimized
libturbojpeg1-dbg - TurboJPEG runtime library - SIMD optimized (debugging symbols)
libturbojpeg1-dev - Development files for the TurboJPEG library
```
This seems to work on all current Debian versions, Wheezy, Jessie and Sid.

Im not sure if Ubuntu has this dummy package.
http://packages.ubuntu.com/search?keywords=libjpeg-dev
Perhaps this should be further discussed.
