Title: Improved roxygen warnings and errors

Hi,

Commits for:
- improve warning and errors by making it clearer that one talks about roxygen tags, e.g.:

```
param require a name and a description
```

becomes

```
@param require a name and a description
```

- fixing an issue with line numbering from srcref, that did not account for empty or comment lines before roxygen chunks.

```
# first line of file
# Standard comments

#' Title
#' @param
fun <- function(){}

```
used to throw an error like:

```
param require a name and a description file.R: 1
```

Here the line number 1 is incorrect which is now fixed into:

```
@param require a name and a description file.R: 4
```
