update module to own version

Currently, a translation that doesn't exist just defaults to the
passed message ID.

It can be helpful to be able to catch these missing cases e.g. to
save to a log.

This PR implements variants ending in 'E' like GetE, GetNE.

This wasn't implemented at the package-level scope, because for
quick translations like that the extra flexibility probably isn't
needed.

+# xgotext
+
+CLI tool to extract translation strings from Go packages into .POT files. 
+
+## Installation
+
+```
+go install git.deineagentur.com/DeineAgenturUG/gotext/cli/xgotext
+```
+
+## Usage
+
+```
+Usage of xgotext:
+  -default string
+        Name of default domain (default "default")
+  -exclude string
+        Comma separated list of directories to exclude (default ".git")
+  -in string
+        input dir: /path/to/go/pkg
+  -out string
+        output dir: /path/to/i18n/files
+```
+
+## Implementation
+
+This is the first (naive) implementation for this tool. 
+
+It will scan the Go package provided for method calls that matches the method names from the gotext package and write the corresponding translation files to the output directory. 
+
+Isn't able to parse calls to translation functions using parameters inside variables, if the translation string is inside a variable and that variable is used to invoke the translation function, this tool won't be able to parse that string. See this example code: 
+
+```go
+// This line will be added to the .po file
+gotext.Get("Translate this")
+
+tr := "Translate this string"
+// The following line will NOT be added to the .pot file
+gotext.Get(tr)
+```
+
+The CLI tool traverse sub-directories based on the given input directory.
