enhancement: let g:asyncrun_status contain command called by AsyncRun

[Konfekt]

The status line indicator g:asyncrun_status could be more expressive if it contained the command called, for example

running grep

if AsyncRun grep was called.

Some people just need a short status indicator, what about a new variable to represent last command ?

[Konfekt]

Yeah, that perfectly solves it.

[skywind3000]

check out latest version, its name is g:asyncrun_info

Some thoughts:

• In case of -program=make -auto=make, it shows -program=make -auto=make. More informative would be simple make. Similarly for -program=grep.
• Perhaps listing the parameters is not necessary?! At least for the statusline, that is.
• The feature seems yet undocumented.

As a general observation:

The solution -program=make/grep to call make/grep is incoherent with all other commands. You should think about adding a command AsyncMake/Grep and using &make/grepprg instead, as proposed in https://github.com/skywind3000/asyncrun.vim/issues/96 .
