SCSS-Lint: new error codes.
Do not `expand()` shell vars

This is especially important when testing/using variables that do not
exist, because then a new shell is spawned by Vim.
But since they should be available already in Vim from the (shell) env
there is no point in doing so.

Cursor columns: fix redraw.
New checker for PHP: PHPLint.
PHPLint: fix syntax highlighting.
Bump version number.
Transform code using pmod_pt module before checking

Helps suppressing the error "parameterized modules are no longer supported" which libraries like ChicagoBoss depend on.
Bump version.
New global option `syntastic_exit_checks`.

Syntastic attempts to catch abnormal termination conditions from checkers by
looking at their exit codes. The "cmd.exe" shell on Windows make these checks
meaningless, by returning 1 to Vim when the checkers exit with non-zero codes.
The above variable can be used to disable exit code checks in syntastic.

New postprocess function: `guards`.

The new function ensures line numbers in loclists are not beyond end of
buffer.  The implementation is very inefficient, because it loads all
buffers in memory.

`eslint` and `lessc` checkers need this function.
The php checkers needs "guards" postprocessing.
Erlang: correctly handle additional LibDirs

The compile function expects a list of paths in the LibDirs parameter,
however when calling erlang_check_file.erl with an additional path (for
example when using the "g:syntastic_erlc_include_path" option), a
string would be passed instead. Because strings in Erlang are lists,
each character of the string would have been interpreted as a lib path.
