tools/vget => tools/v , search, install, etc

Browse Source 
* compiler: rename vget to tools/vpm, implement draft support for v vpm search, v vpm update, v vpm install, v vpm remove, v vpm help .

* compiler: use "v pm" instead of "v vpm" to reduce the redundancy of typing, as suggested by slapden


* Use 'v install modulename', 'v search keywords', 'v update modulename', 'v remove modulename' instead of the longer 'v pm install modulename' etc.

build <module> Compile a module into an object file.
runrepl Run the V REPL. If V is running in a tty terminal, the REPL is interactive, otherwise it just reads from stdin.
symlink Useful on Unix systems. Symlinks the current V executable to /usr/local/bin/v, so that V is globally available.
install <module> Install a user module from https://vpm.vlang.io/.
test v Run all V test files, and compile all V examples.
test folder/ Run all V test files located in the folder and its subfolders. You can also pass individual _test.v files too.
fmt Run vfmt to format the source code. [wip]
doc Run vdoc over the source code and produce documentation.
translate Translates C to V. [wip, will be available in V 0.3]
V package management commands:
search keywords Search the https://vpm.vlang.io/ module repository for matching modules and shows their details.
install <module> Install a user module from https://vpm.vlang.io/.
update [module] Updates an already installed module, or ALL installed modules at once, when no module name is given.
remove [module] Removes an installed module, or ALL installed modules at once, when no module name is given.
