* Remove 'col' from linters where it is hardcoded to 1
When 'col' is 1, the first column will get highlighted for no reason. It
should be 0 (which is the default).
In the scalac linter there was also a check about the outcome of
`stridx`. It would set l:col to 0 if it was -1, and then it uses
`'col': l:col + 1` to convert the outcome of `stridx` to the actual
column number. This will make 'col' equals 1 when there is no match. We
can remove the check because `-1 + 1 = 0`.
* Remove outdated comments about vcol
vcol was added as a default, and the loclists that follow these comments
do not contain 'vcol' anymore
* A try at javac support for ALE
* Small cleanup: moved '/tmp/java_ale' string into script var
* Fixed Travis-CI build failing on autocmd not being in augroup and stupid omission
* One more fix for Travis-CI
* For some reason, expandtab was not set
* Indentation and removal of header guard.
Used examples from ale_linters/c/gcc.vim and
ale_linters/javascript/eslint.vim for the indentation of string concat blocks.
