Add possibility when "koch tools" command is used, nim compiler options
to be passed. The current options are kept and the new user specified
options will be added to the end of the command line if present.
Example:
> koch --latest tools -d:danger --debugInfo --lineDir:on
bin\nim.exe c -o:bin\nimsuggest.exe -d:release -d:danger -d:danger
--debugInfo --lineDir:on nimsuggest/nimsuggest.nim
...
bin\nim.exe c -o:bin\nimgrep.exe -d:release -d:danger --debugInfo
--lineDir:on tools/nimgrep.nim
...
bin\nim.exe c -o:bin\vccexe.exe -d:danger --debugInfo --lineDir:on
tools/vccexe/vccexe.nim
...
bin\nim.exe c -o:bin\nimpretty.exe -d:release -d:danger --debugInfo
--lineDir:on nimpretty/nimpretty.nim
...
bin\nim.exe c -o:bin\nimfind.exe -d:release -d:danger --debugInfo
--lineDir:on tools/nimfind.nim
...
bin\nim.exe c -o:bin\nimble.exe --noNimblePath --nilseqs:on -d:release
-d:danger --debugInfo --lineDir:on dist\nimble\src\nimble.nim
* compiler/msgs: toMsgFilename now operates on FileIndex
* compiler/reorder: use toMsgFilename for compiler messages
* compiler/semstmts: respect listFullPaths for recursive deps error
* compiler/[msgs, options]: make toFilename independent of listFullPaths
toFilename is used mainly in codegen, as such it should not follow
--listFullPaths
* compiler/msgs: use toMsgFilename for toFileLineCol
This proc is mainly used for compiler messages, so it should follow
--listFullPaths
* compiler/msgs: remove toFileLine
unused proc
* compiler/msgs: cleanup toMsgFilename
Also improved path choosing logic, /home should now be preferred over
../home on *nix
* Documentation of NimScript, update and expand, mention the benefits aside of its limitations, add examples, update the list of usable std lib modules
