Terminal Vim

Allow to run GVim or Vim from the AppImage. Which one is started depends on the name used to start the AppImage. If the name starts with 'vim', the terminal version of Vim is started, else GVim is started.

Setup could be:

-rwxr-xr-x 1 ralf ralf 19320200 Apr 28 13:24 GVim-v8.1.1209.glibc2.15-x86_64.AppImage*
lrwxrwxrwx 1 ralf ralf       40 Apr 28 13:25 gvim -> GVim-v8.1.1209.glibc2.15-x86_64.AppImage*
lrwxrwxrwx 1 ralf ralf       40 Apr 28 13:25 vim -> GVim-v8.1.1209.glibc2.15-x86_64.AppImage*

Changes

Using AppImageKit V11

The script scripts/appimage.sh downloads a file name functions.sh. This script uses v6 of the AppImageKit.

Copied some lines from functions.sh to appimage.sh and changed the URLs to use AppImageKit v11 (newest release). Important new feature: ARGV0, see below.

Startup

The gvim.desktop file is changed to call a script named vim.startup.sh. This script ...

Sets the environment variables VIM and VIMRUNTIME (if not already set). With this Vim can cd to other directories and still find its runtime files.
Unsets Python related variables set by AppImageKit. As Python is not packed into the image, we rely on host provided Python.
Evaluates the env var ARGV0 set by AppImageKit. This variable contains the name the executable was started with. If the name starts with vim, terminal Vim is started, else GVim is started. Now you can create a symlink vim.appimage -> GVim*.AppImage to get a terminal Vim.
Returns to the directory the AppImage was started from. AppImageKit sets the env var OWD for this. This fixes #4.

Building

new script scripts/build_vim.sh to configure and make Vim. Also the configuration options are defined in that script. This script is also used on Travis.
reworked the script scripts/appimage.sh

It is now possible to build the AppImage on the local machine:

scripts/build_vim.sh
scripts/appimage.sh

The resulting AppImage is in build/out.

Testing

It is possible to copy the GVim*.AppImage file to vim/src/vim and then start make test.

This is currently not part of the Travis build, but could be added if wanted.
